Anyone know about Template-Toolkit here? Here is my problem:

My application is just about complete and runs just dandy on the development server. I move it to the production server and some of my page stop working -- OK, no big deal, I start track the problem down. I present a number of perl objects and have (perhaps mistakenly) relied on TT's tolerance of undefined values. When I try to access something that does not exist I expect to get undef and I do (and I have for about 4 years of TT usage now). Up on the production box it starts puking errors: undef error - Can't locate object method "blah" via package "blah" at....

I have updated to the newest version of TT on both boxes. The dev is Linux and the production BSD. I tried setting the TOLERANT flag in the TT config. it seems to be behaving like I have the DEBUG_UNDEF flag set (I do not).

I anyone knows about the internals of TT or has dealt with anything similar (or perhaps knows a place where I might find someone who does know) I would be greatful for some help.

Thanks for reading.
