Libmng only needs gzip to compress man files for distribution, so it builds fine without it. The spack gzip currently fails to compile. ``` config.status: linking /var/folders/fy/x2xtwh1n7fn0_0q2kk29xkv9vvmbqb/T/spack-stage/s3j/spack-stage-gzip-1.10-iatwtuk2l5xgwmuh4pwu5bf27yezpydj/spack-src/GNUmakefile to GNUmakefile config.status: executing depfiles commands ==> Executing phase: 'build' ==> [2020-02-14-09:32:45.502913] 'make' '-j12' make: GNUmakefile: Too many levels of symbolic links make: stat: GNUmakefile: Too many levels of symbolic links make: *** No rule to make target `GNUmakefile'.
