I suspect that the netCDF library wasn't compiled using the "-fPIC"
option, which allows it to become part of a shared library.

Try rebuilding the netCDF library -- using the "-fPIC" compiler option
-- and reinstalling it.  Then try rebuilding the netCDFPerl package.
Let me know if this doesn't work.
