I have libtool-2.4 installed in /usr/local/lib. I am not sure whether this is relevant or not though. The problem I see is that libtoolised packages like guile-2.0.11 and glib-2.4 fail with an error like: libtool: link: cannot determine absolute directory name of `(libdir)' I have attached the output of make V=1 to show this. Also attached is the glib config.log I am sending this to bug-libtool because it is a problem with both guile and glib. I hope you can help. Ian
