Forget to install the gtk development packages did we?  Ask for help
next time. :)

Hm.. that' interesting.  lo_send_message_from is a new function in the
latest version of liblo (which has a new maintainer) which I havn't

What version of liblo are you running and where did you get it? (ie
build it yourself, or came with your distro, etc)

Not too crucial, since compiling Om without LADSPA support is something
noone is going to want to do anyway. :)
