I Googled with no helpful result the following:

site:openbsd.org inurl:faq libc httpd

Does this look right?
lou:/usr/lib
$ ls -l libc.*

I upgraded 3.7->3.8 and 3.8->3.9 following the instructions in the 
Upgrade Guide.  What's more, I have rebuilt httpd after applying the 
004_httpd.patch.

I don't have physical access to the machine so this would be my last 
resort.
