Thank you Mel.  You were right about undefined ones;  Here's what I get:

--8<--
apachectl -t
httpd: Syntax error on line 826 of /usr/local/etc/apache22/httpd.conf:
Cannot load /usr/local/libexec/apache22/mod_dispatcher.so into server:
/usr/local/libexec/apache22/mod_dispatcher.so: Undefined symbol "__strdup"
--8<--

Any more trickeries?;-)

Regards,

Joe
