<snip output>

Can you do a "ldd /usr/local/sbin/httpd" ?
Futhermore, it will be great if you can provide me a backtrace.
To get a correct backtrace you have to:
1. Build apache2 and php ports with WITH_DEBUG=yes
2. sysctl kern.sugid_coredump=1
3. set CoreDumpDirectory (ex: CoreDumpDirectory /tmp)
4. do gdb -c /tmp/httpd.core /usr/local/sbin/httpd
(gdb) bt
and copy'n'paste the output.
