Sorry we forgot about this ticket, which is now a year old. Perhaps you are no longer experiencing the problem. If so, we could close this ticket since nobody else has reported a problem like this.

If you are still experiencing the problem, the failure in the log was:

fatal error: 'Security/Security.h' file not found

but there are many warnings earlier in the log for many different OS files, such as:

ld: warning: text-based stub file /usr/lib/libSystem.tbd and library file /usr/lib/libSystem.dylib are out of sync. Falling back to library file for linking.

This is not a warning I've seen very often before, and it may indicate a problem that you should investigate and fix.

Updating to the latest Xcode and command line tools compatible with your OS version is the first thing I'd try.
