Comment:

 Correct: none of the compilers in FSF GCC, including gfortran, support
 -arch flags; -arch flags are an Apple extension. If you would like FSF GCC
 to adopt this Apple extension you'll have to talk to the developers of FSF
 GCC about that.

 The cmake 1.0 portgroup makes no mention of FFLAGS, or any other *FLAGS
 variables. MacPorts base should be smart enough to not add -arch flags if
 the compiler does not support it; we maintain a list in MacPorts base of
 which compilers do and do not support -arch flags. If this is not working
 correctly please provide a reproduction recipe.
