Just to let everyone know this is how Darin's ld work. It searches for shared
libraries through all of the library patches and then if it does not find one,
it searches for a

When you say: the system libraries, where are they? /opt/local/lib?

BTW PR50914, though closed as invalid, indicates that similar mixups can also

It seems I have them in /usr/lib and in /opt/local/lib. How can I find out
which one it picks up?

Sorry, my mistake, it's ~/usr/lib not /usr/lib. I'll have to find out if that
is included in any search path (I doubt it). About the one in /opt/local/lib I

Ok, the one in ~/usr/lib is 2.2.1, so this error wouldn't appear if it got

Sorry, didn't mean to hit Save Changes yet.
In the past I had to configure with

Well, there is the usual problem that if you use external libraries A and B
that are both installed in both path1 and path2 and you want A from path1 and B

You don't need the -L flags for the in-tree libraries at all as you could just
put, say, path_to_mpfr/libmpfr.a on the command line. I understand that this
