    Rob> Hmm, not sure.  What verison of libtool are you using?

address@hidden ~]$ /usr/bin/libtool --version
ltmain.sh (GNU libtool) 1.3.5 (1.385.2.206 2000/05/27 11:12:27)

Did you see my previous email, where I noted that the installed
libguilereadline seemed to want to link against libguile.so.9, _not_
libguile.so.10?  At least, that was my interpretation of the output
from `objdump -x'.  But perhaps that's not really a problem; and in
any case there could be other problems as well.

That sounds right to me, but I don't know what the better check would
be.

One interesting aspect of this problem, if I'm understanding
correctly, is that users will only see it once.  Because as soon as
you configure with --enable-ltdl-install=yes, you then get a more
modern libtool in /usr/local/bin:

address@hidden ~]$ /usr/local/bin/libtool --version
ltmain.sh (GNU libtool) 1.4.2 (1.922.2.53 2001/09/11 03:18:52)

So, assuming that /usr/local/bin overrides /usr/bin, you'd never need
--enable-ltdl-install=yes a second time.
