I have the same problem with both nagios (3.0.6) and nagios-devel (3.1.0); 
the former with either perl 5.8.8 or prerl 5.8.9 and the later with perl 
5.10.  OS is FreeBSD 7.2-PRERELEASE.

Recompling either nagios or nagios-devel but deselecting embedded perl 
results in a successful startup.

Running with embedded perl results in a startup message in nagios.log and 
a segmentation fault in /var/log/messages (signal 11).

I tried following the OpenBSD nagios installation instructions 
regarding .cfg files with 3.0.6, used the default files with a few changes 
to cgi.cfg in 3.1.0; no change in behavior.

A ktrace/kdump didn't show anything very interesting to me, but I'm not an 
expert at reading kdump output (perl is compiled with debugging at this 
point).

Any suggestions?
