========================
Thanks for the reply, Matz.  I discovered part of the answer by studying
the code for rbconfig.rb and mkmf.rb.  But I am still uncertain as to
how far down the installation tree ruby searches for files.  Re: python:
I think python only searched down to a "site-packages" dir, then if it
discovered any files with a .pth extension it read them for an
additional path to search.  Typically, an extension could be installed
as a subdirectory of site-packages, but it could be someplace else. As
part of it's installation it, or you, would put into the site-packages
dir a path file that contained a single line that was a pathname to the
extension's directory.
