I installed Xcode 3.2.6 (and made sure that xcode-select -print-path showed that version), and it still failed.  I cleaned and added -universal...and it still failed.  I did that again adding -quartz...and it found the pre-built binaries.

Yes, I agree, sorry, Mojca responded to me privately that the problem isn't the compiler, it's the +quartz variant, and I confirmed that on my system too. This problem needs to be reported to the developers of tk so it can be fixed.

+quartz used to be the default variant but it was changed last year:
