[mythtv-users] Myth 0.20 main.o won't compile

[Mark]

I am installing a new frontend and main.o keeps failing.  Running Arch 
linux, 2.6.16 kernel, pretty standard devel environment,
up to date, and it's failing with the following output, which I can't 
figure out.  This is the same set of software that I used on the backend
with no issues.  Any ideas?

cd mythtv && make -f Makefile
