Yeah, I got b0rked trying to install zimbra...
Ok -- enough arm twisting, I'm trying to build it ;) -- been on my list
of things to do for a while.
Trying to rebuild the stock rpm now and when I can successfully do that,
I'll add the flags, rebuild, and test.
And the kind folks at jailtime.org
said they would host the rpm and
intructions.
Should have something by lunch.
All I have to do is add "-mno-tls-direct-seg-refs" to the CFLAGS right?
(with gcc version 3.4.3 20050227 (Red Hat
3.4.3-22.1) )?
