How to Make a MacRuby Release

First, build MacRuby.

$ svn co http://svn.macosforge.org/repository/ruby/MacRuby/branches/testing MacRuby
$ cd MacRuby
$ autoconf
$ ./configure --enable-framework --enable-fat-binary --program-prefix=mac
$ make

Then, install it a destination root.

$ sudo sh
$ DESTDIR=/tmp/MacRuby make install

Then, generate the installer.

$ cd misc/release
$ open MacRuby.pmdoc

Then, copy the .pkg file in a MacRuby X.Y directory, with misc/release/License and misc/release/About MacRuby.rtf, generate a .zip file.

Then, upload the .zip file to ruby.macosforge.org/files.
