[AG-DEV] Running AG3 From CVS on RHEL4 Experiences

[Todd Zimmerman]

I should have noted - this _wasn't_ meant to be rant!  Sorry if it came across that way. Just trying
to get a test VenueServer up...

For completeness, here are the versions of the pre-reqs:

Python 2.3.4
ZSI (from cvs) 1.7 released 16-Feb-2005
Bajjer-0.2.3
Twisted-2.2.0 (TwistedSumo-02006-02-12)
ZopeInterface-3.0.1
common - From CVS Feb 21
feedparser-4.1
mDNSResponder-107.5
Bonjour Python module from CVS Feb 21
openssl-0.9.7a-43.4
pyOpenSSL version 0.5.1 from CVS Feb 21
M2Crypto 0.13
