Ynd right you are :-) There's GNU outside of Linux ....

Hmm, from two other often-used libraries: both expat and neon seem to be 
libraries used by many OSS projects. Many seem to distrubute their own version
of these libraries but give the user a chance to use the system installed 
(by means of a configuration option '--with-local-expat' or the like). Same goes
for the Boehm garbage collector ...
Can't guile distribute libltdl but only use it iff there's no local version 
(or if the user states her intention by configure magic)?
