Hi Doug,
Sorry for the delayed response - I just got back into town yesterday so was
'out of action' for awhile.

I upgraded from mod_perl 1.21. Yes I was using dso with the prior
version. Here's some info about the version of perl that I compiled
against:

I uncommented the line and now the server (httpd) just cores when I attempt
to start...

It seems that is cores when it reaches the line for "use Sybase::CTlib;"
in my 'conf/statup_cfg.pl' file.
Now, when I look at the CTlib.pm I notice the following:
package Sybase::CTlib;
require Exporter;
use AutoLoader;
require DynaLoader;
use Carp;
.
.
.
Perhaps something to do with the Exporter or DynaLoader ??
