TexShop @2.47 Build error: Unsupported compiler 'gcc' selected for architecture 'i386'

I get the following error from xcodebuild on Maverick:

Looking into this more, it seems to be a problem with the base SDK. The project includes MacOSX10.4u.sdk, which isn't installed on my Mavericks system. I was able to work around this problem by

1. chown the project folder to make it writable
2. Open the project in XCode
3. Edit the project settings to use the 10.8 SDK (and making 10.8 the target version)
4. Switch compilers from gcc to the default clang compiler
5. Fix some build errors in DocumentClasses/TSDocument-SyncTeX.m (remove return values from a void method)

Note that it won't build for x86_64 due to the dependency on deprecated NSQuickDrawView.

I also had to manually specify /opt/local/bin as my latex path after opening TeXShop. I feel like the installer used to set that up automatically?

Rather than fixing this, I recommend requiring 10.4 <= OSX <= 10.7 for TexShop, and otherwise print a message recommending users install the TeXShop3 port. Or maybe there are now few enough users still <10.7 that the TeXShop port could be upgraded to the v3 series and TeXShop3 deprecated? I don't follow TeXShop development closely, but their website makes it seem like the v2 series is just maintained for legacy systems.
