Omega on OpenBSD with shared libraries

I’m trying to get Omega to work via CGI on OpenBSD with httpd and 
slowcgi.

slowcgi: env[30], SERVER_PROTOCOL=HTTP/1.1
slowcgi: env[31], SERVER_SOFTWARE=OpenBSD httpd
slowcgi: fork: /cgi-bin/omega
execve: cannot load /usr/libexec/ld.so
…
# pwd
/var/www/cgi-bin
# file omega
omega: ELF 64-bit LSB shared object, x86-64, version 1
# pkg_info |grep xapian
xapian-bindings-python-1.4.24p0 python bindings for Xapian
xapian-core-1.4.24  search engine library
xapian-omega-1.4.24 web search application

The issue I’m having is that because slowcgi runs in a chroot 
environment the omega executable cannot load its shared libraries. 
Should the omega executable be built statically in this case? I feel 
like I must be missing something obvious, because I don’t see how the 
OpenBSD Omega package can ever work without completely defeating chroot.

Big thanks in advance,
Andrew
