Well - to be fair, iff you had started your odysee by asdf-ing :mcclim 
instead of just :clim that would've pulled in :clim-looks which pulls in
:clim-clx ...

I've just written up a small patch that does that (without information on 
what to load - in theory it's possible to load backends mcclim doesn't 
know off). But I really think the whole function is kind of unelegant.

 (setq server-path (funcall (get (first server-path) :server-path-parser) 
server-path))

what is this? An entry in a perl obscurity contest? And a lot of semantic 
mud afterwards ... comparing keyword lists with #'equal for shure doesn't 
work.

Hmmm-where to put patches ?

 Cheers, RalfD
