Thread Subject: mex compile error in mac

I am trying to compile a fortran file under mac 10.6 snow Leopard system. The file has been used long in Linux.

The command line for compling the file is simple (dcm.f is a mex file for dc.f)
mex dcm.f dc.f

The error message is
gcc-4.6.0: error: x86_64: No such file or directory
gcc-4.6.0: error: unrecognized option '-arch'

I installed gcc-4.6.0 by the command line
./configure --prefix=/home1/insar/gcc-4.6.0 --program-suffix=-4.6.0 --enable-languages=c,c++,fortran CC="gcc -m64"

Could anybody give me some suggestions? Thanks in advance!

When I removed the -arch option in mexopts.sh, the new error is

Undefined symbols for architecture x86_64:
  "_mxgetm_", referenced from:
      _mexfunction_ in dc3dm.f
  "_mxcopyptrtoreal8_", referenced from:
      _mexfunction_ in dc3dm.o
  "_dc3d_", referenced from:
      _mexfunction_ in dc3dm.o
  "_mxcreatedoublematrix_", referenced from:
      _mexfunction_ in dc3dm.o
  "_mxcopyreal8toptr_", referenced from:
      _mexfunction_ in dc3dm.o
ld: symbol(s) not found for architecture x86_64
collect2: ld returned 1 exit status

Thanks for your help!
