Err, not quite. Modules are .scm files - they're just a way to
restrict namespaces in Scheme. You can load/initialize .so files with
(dynamic-call 'function (dynamic-link "foo.so")).

.lo and .la files are used by libtool. Hmm, generally when I need
shared lib, I just write automakefile (that's Makefile.am) and handle
compilation from there. Now, you need .so files to link with Guile, so
you call dynamic-link with install path and make sure that the .so is
always installed before running Guile.

This works, but makes compile cycle longer (by copying the files).
