Re^4: mod_perl @INC/use base trouble

He won't be happy; rebuilding mod_perl is not always trivial.
You may want to print out @INC from your mod_perl script and verify the paths are correct, and that the user Apache is running under has read rights on all the modules, and read and execute rights on all directories the modules are located in. Your own account and the one mod_perl/Apache runs as are probably different, so mod_perl may have difficulty finding the Class::DBI or Doc::DBI modules because of permissions...
