 Spack follows the naming conventions of Docker, with Dockerhub as the default

+
+Older installations of PGI contains just the old compilers; whereas
+newer installations contain the old and the new.  The new compiler is
+considered preferable, as some packages
+(``hdf``) will not build with the old compiler.
+
+When auto-detecting a PGI compiler, there are cases where Spack will
+find the old compilers, when you really want it to find the new
+compilers.  It is best to check this ``compilers.yaml``; and if the old
+compilers are being used, change ``pgf77`` and ``pgf90`` to
+``pgfortran``.
+
+Other issues:
+
+* There are reports that some packages will not build with PGI,
+  including ``libpciaccess`` and ``openssl``.  A workaround is to
+  build these packages with another compiler and then use them as
+  dependencies for PGI-build packages.  For example:
+
+  .. code-block:: console
+
+     $ spack install openmpi%pgi ^libpciaccess%gcc
+
+
+* PGI requires a license to use; see :ref:`licensed-compilers` for more
+  information on installation.
+
+.. note::
+
+   It is believed the problem with HDF 4 is that everything is
+   compiled with the ``F77`` compiler, but at some point some Fortran
+   90 code slipped in there. So compilers that can handle both FORTRAN
+   77 and Fortran 90 (``gfortran``, ``pgfortran``, etc) are fine.  But
+   compilers specific to one or the other (``pgf77``, ``pgf90``) won't
+   work.

+
+After running ``spack install pgi``, the first thing that will happen is
+Spack will create a global license file located at
+``$SPACK_ROOT/etc/spack/licenses/pgi/license.dat``. It will then open up the
+file using :ref:`your favorite editor <controlling-the-editor>`. It will look like

+   #
+   #   license.dat
+   #
+   # Alternatively, use one of the following environment variable(s):
+   #
+   #   PGROUPD_LICENSE_FILE
+   #   LM_LICENSE_FILE
+   #
+   # If you choose to store your license in a non-standard location, you may
+   # set one of these variable(s) to the full pathname to the license file, or
+   # port@host if you store your license keys on a dedicated license server.
+   # You will likely want to set this variable in a module file so that it
+   # gets loaded every time someone tries to use pgi.
+   #
+   # For further information on how to acquire a license, please refer to:
+   #
+   #   http://www.pgroup.com/doc/pgiinstall.pdf
+   #
+   # You may enter your license below.

-----------------------------
-Specifying ABI Compatibility
-----------------------------
-
-Packages can include ABI-compatibility information using the
-``can_splice`` directive. For example, if ``Foo`` version 1.1 can
-always replace version 1.0, then the package could have:
-
-.. code-block:: python
-
-   can_splice("foo@1.0", when="@1.1")
-
-For virtual packages, packages can also specify ABI-compabitiliby with
-other packages providing the same virtual. For example, ``zlib-ng``
-could specify:
-
-.. code-block:: python
-
-   can_splice("zlib@1.3.1", when="@2.2+compat")
-
-Some packages have ABI-compatibility that is dependent on matching
-variant values, either for all variants or for some set of
-ABI-relevant variants. In those cases, it is not necessary to specify
-the full combinatorial explosion. The ``match_variants`` keyword can
-cover all single-value variants.
-
-.. code-block:: python
-
-   can_splice("foo@1.1", when="@1.2", match_variants=["bar"])  # any value for bar as long as they're the same
-   can_splice("foo@1.2", when="@1.3", match_variants="*")  # any variant values if all single-value variants match
-
-The concretizer will use ABI compatibility to determine automatic
-splices when :ref:`automatic splicing<automatic_splicing>` is enabled.
-
-.. note::
-
-   The ``can_splice`` directive is experimental, and may be replaced
-   by a higher-level interface in future versions of Spack.
