You're probably using binary RPMs not built for your specific system. 
This is a problem with binaries.  Download a current FC4 binary RPM, or 
build one yourself from source.

The "-L/usr/lib/libmysqlpp.a" can be "-lmysqlpp", you know.  And unless 
your program is licensed under the GPL or LGPL, linking statically is 
probably a violation of the license.

This tells you that libmysqlpp was built against a different version of 
the MySQL C API library (libmysqlclient) than is installed on your 
system.  As I said, you need to upgrade the binary RPM, even if you 
don't actually upgrade the MySQL++ version.

No, that's unrelated.  Dale is working on an exotic 64-bit many-CPU SGI 
monstrosity, as I recall.  Weird happenings are part and parcel of that 
world.
