Trying to build tightvnc for FC10 from FC11 src.rpm

[Robert Moskowitz]

Well I got the src.rpm for fc11, and after running rpmbuild, I found a 
number of dependencies I needed.  I installed those and tried again and 
not too supprisingly the rebuild failed.

First it is telling me that both user and group mockbuild do not exist 
and it is using root.

Is this a problem?  I am running from userid:  me


After these warnings, I get an Executing(%prep) and a number of info 
messages, then after a line about 'patching file configure.ac' I get:

Hunk #1 FAILED at 29.
Hunk #2 succeeded at 53 (offset 2 lines).
Hunk #3 succeeded at 1213 (offset 10 lines).
Hunk #4 FAILED at 1892.

Hunk #2 FAILED at 478.
2 out of 2 hunks FAILED -- saving rejects to file mi/miinitext.c.rej
error: Bad exit status from /var/tmp/rpm-tmp.lr6xIj (%prep)

So what do I do to get this working?
