Comment (by kencu):

 some kind of an issue with the way arch is being set, it appears:
 {{{
 /usr/bin/clang -I/opt/local/include
 -isysroot/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX13.sdk
 -D_ISOC99_SOURCE -D_FILE_OFFSET_BITS=64 -D_LARGEFILE_SOURCE

 clang: error: no such file or directory: ''-arch'; did you mean '-arch'?
