Hello.

Thank you for your reply.

But then how do the databases/dbXX ports achieve the same result
without it? I thought it should find it since there is a symlink
in /usr/local/lib that points to it. I want that when I compile a
program with -L/usr/local/lib/test -ltest it actually links to test-2
for example. Please look at the dbXX ports to see what I mean.

Best Regards,
Ale
