I don't know how to get in contact with the dev for Plugman. His Web site has no area for Plugman and to comment about Plugman over at the WPMU site where the code is hosted I have to create an account and I don't feel like doing that.
Plugman doesn't call the WP actions that some plugins use to activate themselves, which in some cases breaks the plugins since they don't automagically create tables and other stuff as they should.
So here's a fix that needs to go into plugman.php if anyone knows how to contact the dev:
In the activate_plugin function, right before echoing "Done!" add this:
do_action('activate_' . $plugin);
And in the deactivate_plugin function add this:
do_action('deactivate_' . $plugin);
Thar she blows!!!
