Comment (by larryv@…):

 Update:

 - The latest versions of apbs (r104099) and apbs-mpi (r104106) do not
 require GCC at all.
 - I’ve closed #38261, adding variants to ccpnmr (r104107) and pdb2pqr
 (r104108).
 - I’ve closed #38260, updating libxc and adding variants (r104109).
 - I’m just going to update offlinefs to require gcc47 and not bother with
 variants.

 New diff attached.
