This is a common error I've seen from time to time in several ports. The
fix is to always use libraries from the build directory when available and
prefer these to those in /usr/local/lib.This can be rather tricky, though
it is usually "just"  matter of correctly ordering the -L arguments for the
link.

I'd guess that the problem is in "demos" since it links executables against
libchamplin, but I am not a make expert and especially so when libtool is
used.

There is quite possily a standard way to deal with this and my wild guess
would involve the definition of pkglibdir in demos/Makefile.
