Are you sure that libltdl from libtool-2.4 is being used?  The dtruss 
trace (from Michael Ellis) at 
http://lists.gnu.org/archive/html/bug-guile/2011-03/msg00020.html 
shows insecure accesses more like I would expect from a libtool 
version suffering from CVE-2009-3736, which is very dangerous under OS 
X.  See

   http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2009-3736

The recommended portable way to load modules is via a libtool module 
.la file.  It is also recommended to load modules via a full path 
rather than via a search path because the search path might not be as 
secure and predicable as you might like.
