cmu-sphinxbase: require a Homebrewed Python

Compiling against system Python causes a compiler mis-match.
This can be worked around, but as a workaround suggest using
a Homebrewed version of Python instead.

+    Compiling against the system-provided Python will likely fail.
+    The system-provided Python includes PPC support, which will cause a compiler
+    mis-match. This formula is known to work against a Homebrewed Python.
+
+    Patches to correct this issue are welcome.
