Finally - some free time to compile :).

I just got done compiling a static version mod_perl inside the httpd.
After modifying the config file to match my 'dynamic' httpd (ie. adding the
PerlRequire with a different config.pl file that has a 'use Sybase::CTlib;'
in it.), I fired it up and...no core dump or segmentation fault.  And, I'm
now able to successfully query my db.  So, it looks like something is wrong
with DSO and perl...the dynaloader ???  Any ideas ??

Here's my perl -V:

[root@hsimrhpc1 logs]# perl -V
