Mac build instructions unclear

[beOn]

The readme section on the mac install process starts with the words: "With a different Python distribution..."

Different than what?

Actually, the whole line refers to things that aren't clear:

With a different Python distribution: in the same file, edit HEADER_SEARCH_PATHS and LIBRARY_SEARCH_PATHS to the proper places so that ZeroMQ may be found.

"in the same file" <-- ??
