If the user has *no* version of the lib (i.e. not the gem and not the
regular version) you would get into an infinite loop here.


In Instiki/Pimki we tackle this like so: the tgz includes the libs
needed, while the gem version does not but does specify them as
dependencies. When starting we test if this is a gem or not and know
how to require the necessary libs. Does this help?
