The configure output on the buildbot and on my system shows that as long as llvm-gcc42 is installed, it finds the MacPorts version of llvm-gcc42 instead; I guess find_developer_tool also looks in ${prefix}.

We do not look in ${prefix} specifically. It's actually xcrun/xcodebuild
that also seems looks in PATH for the tool,
from my OS X 10.9 Mavericks with Xcode 5:

  $ xcrun -find llvm-gcc-4.2
  /opt/local/bin/llvm-gcc-4.2
  $ xcodebuild -find llvm-gcc-4.2
  /opt/local/bin/llvm-gcc-4.2

I am also wondering if this is actually the intended behavior or just a
coincidence?
