When I try to compile a test program I wrote I get the following: > gfortran -c test.f95 gfortran: installation problems, cannot exec 'as': No such file or directory I'm running gfortran from a Mac with OSX Panther. Any suggestions? Amy W. ************************************************************ Amy E.
