I did have linking problems on some packages but I don't remember the
details, linking problems are common with GNUstep... I will test these
packages but you'll have to be patient. I usually only test on wheezy
64 bits so I will have to setup a vm for precise (don't want to mess
up the real one !). 

Are you using the 32 bits version ?
