You are correct - I already had this once - 
Apache strips binary during "make install" 
( http://perl.apache.org/guide/debug.html#gdb_says_there_are_no_debugging_ )

So I have reinstalled it:

pref# httpd
Segmentation fault (core dumped)

And no, it's not mod_perl.so related - I get the same 
when I comment the line in /var/www/conf/httpd.conf

#LoadModule perl_module        /usr/lib/apache/modules/mod_perl.so

So, there is a problem with httpd in OPENBSD_2_9, when 
the ServerName is unset in /var/www/conf/httpd.conf.
