If you search our issue tracker:

https://trac.macports.org/query?status=!closed&summary=~mythtv

you should find the ticket describing this problem:

https://trac.macports.org/ticket/36854

Unfortunately no solution is mentioned there.


Although it will not help with this specific issue, you should absolutely upgrade to Xcode 3.2.6, since it is the last free version of Xcode for Snow Leopard and the one everyone else is using and testing with.

Some users say that Xcode on Snow Leopard is upgraded via Software Update; our Guide even claims this is the case. However I've never seen that occur myself, and it was never that way on prior or subsequent versions of OS X. If Software Update does not offer Xcode 3.2.6 to you, then you should download it manually from ADC and install it. The link to do so is in our Guide:
