Thanks Michael!

This explains why my cludge fix that I described sometime ago worked 
(sortof). I had been removing the *.so files from the sybase directory 
when building sybperl and sticking them back afterword. That would force 
the DBlib.so file to include the *.a version of the file and produce a 
much bigger shared library. Removing the -ldb is much more elegant and 
produces a MUCH smaller DBlib.so file. All of the tests seem to work 
properly and a sampling of my scripts also work.

The question that I have is: Does the removal of -ldb from config.sh 
remove any functionality from perl or is it harmless?
