pgf77 is not recognized

I installed PGI Accelerator Fortran Workstation 13.7 on a drive running Mac OSX 10.8.5 (Mt. Lion) but when I enter pgf77 -c the command is not recognized. What have I missed in the installation?

Make sure your environment is set up

setenv PGI /opt/pgi
set path=($PGI/osx86-64/13.7/bin $path)

Please post the outputs of

  1. which pgf77
  2. which pgfortran
  3. pgf77 -dryrun hello.f
  4. pgfortran -v hello.f
  5. gcc -v hello.c

or send them to
