Summary: [PATCH] 1.8.3 ruby.c doesn't compile on OS X due to missing char **environ

Initial Comment:
Hello,

I'm working on getting Ruby 1.8.3 into Fink, the Debian style
package managed system for Mac OS X.

Ruby 1.8.3 introduced the usage of the

extern char **environ;

in ruby.c.

Mac OS X does not have this symbol, which you can confirm by greping
through /usr/include and nm on the /usr/lib/*.

The work around is to do something like this:

--- ruby-1.8.3.org/ruby.c       Tue Jun 28 15:09:58 2005
+++ ruby-1.8.3/ruby.c   Sun Oct 16 23:42:31 2005
