mpich removed subports that other ports still use.

[ryandesign (Ryan Carsten Schmidt)]

Some old compiler subports were removed from mpich but other ports still have variants that declare dependencies on the removed subports.

This causes ​failures of our distfile mirroring job, which attempts to mirror each variant.

For example, the mpich-gcc47 subport was removed, but here is a list of ports that depend on mpich and that still have gcc47 variants:

$ port echo depends:mpich and variant:gcc47

I guess those variants should be removed from those other ports.

We ​still see failures in our distfiles mirroring scripts because of this.

Somebody please fix.

AFAIK, these have all been resolved:

$ for p in openmpi mpich ; do for v in clang{33,34,37,39,40} gcc{44..48} ; do printf "Checking for ${p} variant ${v}\n" ; port echo depends:${p} and variant:${v} ; done ; done
