DBDriver unset

[Timothy J Nolte]

I'm trying to build a simple Chameleon app using the App Dev Guide. Whenever
I try to test the app I get:

[Fri Jul 13 13:05:30 2007] [crit] (70023)This function has not been
implemented on this platform: DBD: driver for [DBDriver unset] not available
[Fri Jul 13 13:05:30 2007] [crit] (70023)This function has not been
implemented on this platform: DBD: failed to initialise
[Fri Jul 13 13:05:31 2007] [notice] child pid 2534 exit signal Segmentation
fault (11)

This is while tailing the apache error_log. I've tried other full-blown apps
and had the same error. I have been able to run some sample apps under
MapServer but not this simple one. Any ideas, anyone?
