This script needs an existing MIT/GNU Scheme installation to function,
but the program \`${MIT_SCHEME_EXE}' does not appear to run it.

If you have installed MIT/GNU Scheme in an unusual location, set the
environment variable MIT_SCHEME_EXE to the name or pathname of the
MIT/GNU Scheme executable, which is usually \`mit-scheme' or
\`/usr/local/bin/mit-scheme', and set the environment variable
MITSCHEME_LIBRARY_PATH to the pathname of the MIT/GNU Scheme library
directory, which is usually \`/usr/local/lib/mit-scheme-ARCH', where
ARCH is the compiled code architecture, such as \`c', \`i386', etc.
