Why do you describe the installation of the library as separate from 
compiling the examples?  I assume you are building the library from the 
tarball, where running 'make' at the top level builds the library and 
then the examples.  You don't install the library between the two steps.

Not that installing the library is a problem here.  It's just not 
necessary, because the examples in the tarball look in ../lib for the 
headers and libraries.  I just wonder if you are doing something odd 
when building the library.

Aha, a MacOS X system, then.  Nobody has yet reported success (or 
failure, for that matter) on this platform.

libtool should handle the library linking issues for you here.  If you 
are building the library correctly, the only thing I can suggest is to 
maybe search the archives on the libtool mailing list to see if this 
sort of problem is common on OS X still.  Maybe upgrading X Tools or 
just the autotools suite will fix the problem.
