Hi
My english is not good (sorry) but I try to explain my problem
I have apache2.2.9 with modperl 2.0.4 static; I have some perl modules
(development by me) with Sleepycat::DbXml library; when ran "make test"
for its modules all is fine (I also develop the test); I also use mason
(1.37).
When i tried to acces some page generated for maso I gotten the next
messages (log/error):
/usr/local/apache2.2/bin/httpd: symbol lookup error:

if I execute "ldd
/usr/lib/perl5/vendor_perl/5.8.8/i686-linux/auto/Sleepycat/DbXml/DbXml.so"

This looks ok, but I'll defer to the wisdom of those with more ldd-fu.
my distribution is gentoo...
maybe the problem is caused by
- duplicate libraries with different versions
- or old libraries
I updated my system and delete duplicate libraries, but the problem
continue
anybody can help me? .... where can investigate?
another question is: why the problem is present only with apache?
Try rebuilding apache and mod_perl - it may be trying to load a version
of DbXML at runtime different than what it was built with. I've seen
similar problems in the past and rebuilding mp/httpd is usually a good
fix after eliminating the duplicate libs.
