Comment 4 for bug 217792

You all might be interested in knowing that I found a workaround. Just download the portable C sources for the latest MIT-Scheme from http://www.gnu.org/software/mit-scheme/ and follow the instructions to build. The compilation takes an hour or two but went off without a hitch and MIT-Scheme works fine. I couldn't get edwin to start but just dropped (require 'xscheme) in my .emacs and was right as rain.
