Came here to report the same issue.

OSX 10.11.1, with latest XCode (7.1.1)

This is blocking me from installing gcc-4.5 which I need for a project, so any help would be much appreciated.

[Baaaaam (Mouginot Baptiste)]

I got the same issue with gcc4.9 and Xcode 7.1.1

Temporary fix: change file /opt/local/include/libunwind.h

change line number 17 to #include <libunwind/config.h>

[Baaaaam (Mouginot Baptiste)]

I have just downgrade to Xcode 7.1... which solve the problem also :)
