Pallet can not install/compile with Xcode 5.1.1

[waitsnake@…]

I tried to install Pallet with Macports 2.3.0 on OSX 10.9.3 with Xcode 5.1.1 (5B1008) but it did not work. Xcode 5.1.1 comes with clang-503.0.40.

The build logfile shows the following error when using this compiler:

error: garbage collection is no longer supported

As workaround I did the following:

1. "sudo port install clang-mp-3.5"
2. I try to force that this compiler is used: "sudo port install Pallet configure.compiler=macports-clang-3.5"
   -> but it was still not working
   -> I saw in build_log that it uses clang from xcode anyway (Is the compiler hard coded in build script ???)
3. now I try to change the Xcode compiler manually "cd /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin"
4. "mv clang clang_xcode"
5. "ln -s /opt/local/bin/clang-mp-3.5 clang"
6. "sudo port install pallet" ->installing of Pallet works now without error and the program runs fine (well except from that fact that Pallet can not find not the /Library/Tcl directory, but this will be an other ticket...)

For the problem with the Tcl directory that I mention in the description here I wrote the ticket #43923.

The Pallet port does not hardcode the compiler, but it uses Xcode, and Xcode cannot use arbitrary compilers, without some fiddling. But you should undo the changes you made in /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin.

The "garbage collection is no longer supported" bug is already reported in #43581.
