You're right, it doesn't.  The port also doesn't support universal 
building.  I freely admit that I know very little about c/c++/objc 
compiling and linking although I've learned quite a bit in the last 
1.5 years working on this port.

What I had noticed was that quite a few compile/link flags were being 
duplicated somewhere in the build toolchain: 
MacPorts/configure/qmake/XCode/whatever.

In light of that and last fall's build problems 
(https://trac.macports.org/ticket/35934), the approach of clearing 
all these flags--ala the qt4-mac port--looked interesting.  BINGO. 
Much cleaner builds on XCode 3.2.6, working build with clang from 
XCode 4.6.mumble, plus a working build on a 32-bit Core Duo machine 
for the first time.  IOW, huge improvement.

Nonetheless, I take your point.  I will look for a way to pass the 
desired arch to Myth's configure.  For mythtv-core.27 (0.26 is 
unworkable on OS X), I'll can have a look at a universal build.
