Does the nscache.so module actually exist in the bin directory? For AOLserver 3.2+ad12 and AOLserver 3.3.1+ad13, if you're building from the source tarball, nscache.so, nssha1.so, and nsrewrite.so need to be compiled manually. The Oracle database driver, pgdriver, and other things like nsopenssl also need to be compiled manually. I've never used the RPMs myself.
