Comment (by ryandesign@…):

 From the patch, those ports are:

  * lua-numlua: the compiler to use needs to be updated in the patch file.
 Yes, this could be changed so that variants could be added (placeholder in
 patchfile; reinplace in portfile)
  * offlinefs: I'm unable to determine why this port depends on gcc4* at
 all
  * p5-extutils-f77: the patch was already updated to use 4.7, and it too
 could be changed so that variants could be added
  * apbs: yes variants could be added
  * apbs-mpi: I'm unable to determine why this port depends on gcc4* at all
  * ccpnmr: the patch needs to be updated with the new compiler; yes
 variants could be added
  * ds9: yes variants could be added
  * lanHEP: yes variants could be added
  * libxc: yes variants could be added
  * pdb2pqr: yes variants could be added
