old code questions

 
I've been hacking on yum 2.0.8 and rpm for an internal enterprise wide
solution. I've got just about everything figured out except how to get
yum to look at an RPM database other than the default /var/lib/rpm. I've
spent most of the day on the debugger and haven't quite got there. 

Trying to figure it out I get

Downloading Packages
Getting try_4-3.0-9.x86_64.rpm
Getting try_3-3.0-1.x86_64.rpm
Getting try_1-4.2-1.x86_64.rpm
Running test transaction:
error: cannot open Basenames index using db3 - No such file or directory
(2)
Segmentation fault

This could be due to our screwy python install as the segv seem to be
during the return from a callback class RPMInstallCallback after a pass.


Any help.

Please.
