For anyone going to take a look at this, I've found it fails
under FreeBSD 4.8 whether it's running in a jail or not.

Is there an easy way to build all this (apache, ruby-mysql,
mysql client libs, etc.) debug and run it under gdb so I can get
useful information?  It's been quite a few years since I've
debugged with gdb.

Thanks in advance for any help.
