Great, I've committed the fix to CMake:

  FortranCInterface: Fix PathScale detection again
  /cvsroot/CMake/CMake/Modules/FortranCInterface/my_module_.c,v  <--  Modules/FortranCInterface/my_module_.c
  new revision: 1.2.2.1; previous revision: 1.2

and staged it for inclusion in 2.8.1.

That should work.  If Trilinos needs other flags it should
be appending to the user-specified (your) value, not replacing.

IMO Trilinos needs to be fixed to define this flag automatically.
This is a separate issue to bring up with developers of Trilinos
proper.
