This is the trick I use in my Makefiles. I need to find clang's version to pick 
the directory from which I can take clang's include files.

# Get the clang version.
VERSION := $(shell $(ELLCC)/bin/ecc -v |& grep version |& sed "s/.*version 
\([0-9]*\.[0-9]*\).*/\1/")

I wish there were an easier way.
