Sorry to take so long replying.  We're shorthanded this week and
trying to get out the final release of 3.6.0 (maybe later today).

What you are seeing in the output from "make test" when it is testing
the old netCDF version 2 Fortran interface, are just warnings, not
errors:

  Making `test' in directory /Users/delire/Desktop/netcdf-3.5.1/src/fortran

  + g77 -c ftest.F
  ftest.F: In subroutine `tncacpy':
  ftest.F:187: warning:
                 call ncagt (outcdf, NCBYTE, attnam, bytval, iret)
                      1
  ftest.F:196: (continued):
                 call ncagt (outcdf, NCGLOBAL, attnam, shval, iret) 
                      2
  Argument #4 of `ncagt' is one precision at (2) but is some other precision at

  ftest.F:187: warning:

  ...

These are expected, because the old version 2 interface used type
punning to return values of multiple types in the same argument.  All
the tests work after these compiler warnings, so you can ignore them.
They aren't the result of something wrong with g77, but are to be
expected.

Since the Fortran tests ran fine using g77, I don't think the cause
of your "bus error" is the netCDF library.  If you compile and link
your Fortran program the same way they are compiled and linked in the
test:

  g77 -o PROG -I/Users/delire/Desktop/netcdf-3.5.1/include PROG.f 
-L/Users/delire/Desktop/netcdf-3.5.1/lib -lnetcdf

(where PROG is the real name of your file/program), it should work
fine, just as the tests did.  If you can isolate a small example that
fails and send it to us, we could try to reproduce it here.  The fact
that it worked on the G4 but not on the G5 may mean you have to
recompile everything that's used in the Fortran program, not just the
netCDF library.
