When building python, I get:
... mapping ./python/dist/src/Include/pyport.h
... mapping ./python/dist/src/Include/pystate.h
cannot change permissions on temporary directory
Operation not permitted
... mapping ./python/dist/src/Include/pythonrun.h
... mapping ./python/dist/src/Include/pythread.h
... mapping ./python/dist/src/Include/rangeobject.h
... mapping ./python/dist/src/Include/sliceobject.h
it doesn't seem to be a fatal error though.
