[kforge-dev] [kforge-user] trac plugin / installation issue

Wed Oct 27 11:05:40 UTC 2010

Hi Gert,

Can you actually get Trac running on its own? I think once you can do 
that, KForge would be okay. Since you're on Lenny, I think you've been a 
bit unlucky. Perhaps others on this list have some suggestions, or 
common experience?

Best wishes,

John.
