libextutils-f77-perl 1.16-2 (amd64 binary) in ubuntu lucid

 This module tries to figure out how to link C programs with
 Fortran subroutines on your system. Basically one must add a list
 of Fortran runtime libraries. The problem is their location
 and name varies with each OS/compiler combination!
 .
 This module tries to implement a simple
 'rule-of-thumb' database for various flavours of UNIX systems.
 A simple self-documenting Perl database of knowledge/code
 for figuring out how to link for various combinations of OS and
 compiler is embedded in the modules Perl code. Please help
 save the world by sending database entries for
 your system to kgb@aaoepp.aao.gov.au
 .
 The library list which the module returns
 can be explicitly overridden by setting the environment
 variable F77LIBS, e.g.
 .
   % setenv F77LIBS "-lfoo -lbar"
   % perl Makefile.PL
