Hi Susana,
  Before you compile the Fortran bindings, you'll have to have
already compiled the plugins themselves. Did you compile the plugins
before trying to compile the Fortran bindings? If so, there should be a
"compile" subdirectory in your plugin tree containing the plugin libraries
and header files, which is the first step in the process to linking them into
your Fortran code.

Cheers,
  John Stone
