David, some discussion on your changes:

I suspect that most people will _not_ be building
the backend for a while, so I would like to leave that
default as is. How about a '--enable-backend' flag?

I guess we should have a variable up near the top
to select a particular mirror. I have added:
our $sourceforge = 'http://internap.dl.sf.net'

Indeed. Will check in that change now.

Thanks. It will come in handy.

That doesn't seem to be needed for a frontend build against
QT/Mac 3.3.4, so I have left it out for now.

Weird. The build just works for me. Are you using a newer GCC?
% gcc --v
Reading specs from /usr/libexec/gcc/darwin/ppc/3.3/specs
Thread model: posix
gcc version 3.3 20030304 (Apple Computer, Inc. build 1495)

That is not a correct fix. The OS X frontend
does not use _any_ X11 code. Nada. Ziltch.
If something is trying to pull in X11 stuff,
then _it_ needs to be fixed.
I will do a --enable-backend build next,
and see if I can reproduce this fault.
Is it possible that you have a Qt/X11 build
(e.g. Fink's) that is somehow being referenced?

Hmmm. My 10.3.9 install has it:
% which distcc
/usr/bin/distcc
I am not sure why it is often enabled,
but configure lets you turn this off:
% ./configure --disable-distcc
# Basic Settings
Compile type release
Compiler cache no
DistCC no
...
% head config.mak
# Automatically generated by configure - do not modify
PREFIX=/usr/local
QMAKE_CC=cc
(instead of the default:
% head .osx-packager/src/myth-svn/mythtv/config.mak
# Automatically generated by configure - do not modify
PREFIX=/Volumes/MythOSXbuild/.osx-packager/build
QMAKE_CC=distcc cc
)

Why increase this? The previous size is plenty big enough
for the frontend plus some extra growth (extra plugins, a few
archived copies of the frontend, et cetera). Bigger means that
people need that much extra space on their disks to actually
create the image.
