Comment 3 for bug 373018

"hillma" pointed out on #ubuntu-devel IRC that there's an amd64 version of mit-scheme in Debian now, so I bootstrapped it for Ubuntu vivid based on that. If you need it for older releases of Ubuntu, the binary package from the build I just did is downloadable from https://launchpad.net/ubuntu/+source/mit-scheme/9.1.1-5/+build/6558575 and its dependencies are satisfiable back as far as Ubuntu 12.04, so you should be able to install it by hand using "dpkg -i" or similar.
