[I'm not on the bug-libtool list, so please cc me.]
Despite being reported a year ago, Guile can still not open dynamic libraries
ending with .dylib on Mac OS X. Looking throw the past discussion, it looks as
though developers of the one package hold the opinion that those of the other
package should do the fix. So I am merely reporting it, cross-linking, so that
you can figure out who guys should do the fix. :-)
So guile-2.0.0 using libltdl.7.dylib of libtool-2.4, can on Mac OS X 10.6.6
only open a dynamic library if the name of what it actually opens ends in .so
(say by making a soft link using 'ln -s'); if it ends in .dylib, it cannot open
it, even if the full name is given.

Mac OS X does not care about file name extensions; .dylib is just a convention
for native dynamic libraries.
So the wanted behavior is to first try opening a library without adding an
extension, and then try out different endings. On Mac OS X, it would be best
trying out .dylib first - I haven't seen any other ending in use.
