Didn't really give a very good account of this - crap post. Sorry, I'll try
to elaborate.
On Windows, we're relying on this code in F77.pm:
$F77config{MinGW}{GFortran}{Link} = sub {
# do stuff
return( "-L$dir -L/usr/lib -lgfortran -lquadmath -lm" );
};
Now, I can change the return to:
return( "-L$dir -L/usr/lib -lgfortran -lquadmath -lm -lrubbish" );
where "-lrubbish" is a non-existent and unlocatable library.
Having made that change, it makes no difference to the usability of
ExtUtils-F77. It still builds, tests and installs fine:

When it comes to building PDL using this EU-F77 installation, Slatec and
Minuit still build fine.
Firstly, during the 'Makefile.PL' step I find:

As you can see, EU-MM removes the link to the unfound librubbish library on
both occasions, thus avoiding what would otherwise be fatal errors.
And then PDL-2.014_01 builds and tests fine (including slatec and minuit).
So ... are you sure that linking to non-existent libraries is really an
issue ?
The removal of links to unlocatable libraries is a design feature of EU-MM,
and works on all systems afaik.
Cheers,
Rob
