Amazon Linux doesn't package mit-scheme (neither does CentOS I think)

wget https://ftp.gnu.org/gnu/mit-scheme/stable.pkg/9.2/mit-scheme-9.2-x86-64.tar.gz
tar xzvf mit-scheme-9.2-x86-64.tar.gz
mv mit-scheme-9.2 mit-scheme-9.2-binary
cd mit-scheme-9.2-binary/src
./configure
make
sudo make install
cd ../../
# Patch the source of MIT Scheme and reinstall the patched version
