Jeremy, I believe the mythtv-core.25 port will only work (on XCode 
4.5) _IF_ the user already has apple-gcc-4.2 installed.

I would classify this as a bug in the current implementation of the 
compiler.fallback list.  MacPorts tries to use the first fallback 
compiler that isn't blacklisted.  When apple-gcc-4.2 is chosen, there 
is nothing to ensure that it is installed or added to the 
dependencies until 32542 is fixed.

BTW, it seems to me that the compiler.fallback should be an ordered 
list with the port author in control of first, second and other 
choices?  In my case, apple-gcc-4.2 works but results in some 
(non-fatal) errors at runtime; macports-clang-3.0 generates 
quieter-running code.


Bradley, I believe if we add apple-gcc-4.2 to the blacklist, 
mythtv-core.25 will work predictably again.  Could you please change 
line 84 from:
                     dragonegg-3.0 dragonegg-3.1
to:
                     dragonegg-3.0 dragonegg-3.1 apple-gcc-4.2

Thanks,

Craig
