Problem is that the $(LDFLAGS) variable in the Makefile.in for several 
components comes AFTER some library refrerences in the link line.  The 
libraries referenced (for instance lber) will not be found, because their 
locations are defined in the LDFLAGS variable.  Here is a diff from the 
Makefile.in from the CVS tree of 10/20/2003, and the one I modified to get it 
to get past this issue:

recommendation:  I think it would be fine to just move the LDFLAGS variable 
before the library references.
