* Add package for vcftools@0.1.14
The package munges the various perl scripts so that their sbang lines
point to the depended upon perl (perhaps with Spack sbanger in the
dance) instead of relying on `/usr/bin/env perl`.
As it stands it installs its Perl libraries into `prefix/lib` and then
depends on `setup_environment` to prepend that dir onto PERL5LIB.
See my [vcftools issue
80](https://github.com/vcftools/vcftools/issues/80) for a discussion
about fixing its non-functional attempt at isolating itself from
PERL5LIB shenanigans.
* perl dependency should be build/run
