libtool 1.4.3 searches /usr/lib before -L<dir>

I've asked for help about this problem twice in the last
few weeks, without any replies.

In the meantime I've done some searching in the libtool
list history, and I came across this:

This seems to be exactly the same problem I'm having.

Now I'm wondering, has the reason, and possibly a
solution for this problem been found in the meantime?

Regards,
