32 bit fortran library?

[Joy Romanski]

Hi,

I can't seem to get any of the OpenGrADS extensions to run.  I have GrADS
1.9.0-rc1 installed on my MacBook Pro (OS X Tiger), and I also have the
extension files, and have added the appropriate lines to my .profile file.
When I run "hello" from the GrADS prompt, I get this:

ga->hello
dlopen(libhello.gex.dylib,1): Library not loaded:
/usr/local/lib/libgfortran.3.dylib
  Referenced from:  /usr/local/bin/gex/libhello.gex.dylib
  Reason:  no suitable image found. Did find:
      /usr/local/lib/libgfortran.3.dylib:  mach-o, but wrong architecture
      /usr/local/lib/libgfortran.3.dylib:  mach-o, but wrong architecture
Unknown command: hello
ga->


Further investigation suggests that the problem is that I have 32-bit GrADS,
but a 64-bit fortran library.  I tried downloading several different fortran
compilers (gcc, gfortran and g95), but haven't found one that works.

Has anyone else had this problem?  Any suggestions on how to fix it?

Thanks!
