Are you running this from the command line or a browser ?
Browser : run it from the command line. If you are calling <code lang="perl">die()</code> before you print a header, the prowser would print nothing.
Command line : It appears that there is still something wrong with a path setup somewhere, and the mysql.so file is not getting loaded. It usually will not go into a black hole like that (it usually prints a cannot load message like make test did), but i have seen DBD::Sybase do this on rare occasion. So, back to the path issue from your other posts
i had a memory leak once, and it ruined my favorite shirt.
