Build Distribution & Speech problem

[use-revolution-admin at lists.runrev.com]

I didn't know some externals were necessary to use the revSpeak 
command, and from Alex and SIm's posts I can't gather what I have to do.

- which files are necessary?
- where do I get them?
- where do I put them?

I am using macOS 10.2.6 and want build distributions for macOS, macOS X 
and Windows.

Thank you

Manuel
