I'm pretty sure that you don't need a custom XCode install. The 10.6
SDK comes with XCode for OSX 10.9 (or you can install it from inside
XCode). You do need to set all the right flags though. I beliieve
these are all, but I don't have a Mac to verify now.

-mmacosx-version-min=10.6 -isysroot/Developer/SDKs/MacOSX10.6.sdk
-DMACOSX_DEPLOYMENT_TARGET=10.6

Apart from that, I think the solution for regular and consistent
builds that many can contribute to is to get the build scripts
upstream, and set up continious integration.
TravisCI is free for open source projects and can build for Mac OSX.
