does the libdb distribution create links to libdb.so

I am working with Ubuntu 8.04 and trying to install AppWeb web server (http://www.appwebserver.org/) with PHP 5.2.6 support. I can get it to compile just fine if I symlink libdb.so to libdb.so-4.x (where x is anywhere from 2 - 6), which is what the install is looking for, however I thought that new versions of libdb should symlink to libdb.so-new.version to libdb.so (all files in /usr/lib).

Am I wrong in my assumption? Should you have to install libdb-dev to get a link automatically created for libdb.so ?

I think installing libdb-4.6 should automatically symlink libdb.so-4.6 to libdb.so .

Thank you for any help you may be able to give me (education on correct package building etiquette included)!
