The problem with using fortran from within IDL is that the fortran
libraries aren't already in memory. You'll need to do something to ensure
the fortran libraries are loaded either by statically linking them with
your .so or by calling a fortran function that expects no parameters in
a call external for example

IDL> b=call_external("/usr/lib/libF77.so.1.4","getpid_")

Be warned, however, that this second method could result in other undefined
symbols if there are multiple fortran librarues.
