I guess that my problem originates in my not knowing how to specify
the appropriate typemap during the build process. I currently
use Module::Build::Pluggable ('PDL', 'Fortran');
in my Build.PL, but I have found no information in the Module::Build
and related packages on how to setup the typemap. I'll appreciate any
advice.
Regards,
Luis
