I received a FORTRAN program with a whole lot of Makefiles in it. My compiler uses pgf90 for the compile command instead of just f90. I tried making an alias for f90 to equal pgf90. That works fine on the command line, but when the Makefile runs, it doesn't work. Is there any other way I can make the pgf90 command work with f90? For various reasons, going in and changing all the makefiles is not an option.
