The new recommented way
Since rscheme.org is too often down,
it is recommented to install
RScheme
version 0.7.3.4-b7 or above
from
copy at askemos.org.
Please refer to
How to install RScheme on your system.
On debian don't forget to install the required -dev packages, e.g., zlib1g-dev for compressed repositories.
1a Install from CVS
Install libgmp, since we are going to compile Rscheme with full numeric tower support.
Run the (now unsopported) INSTALLFreshRScheme Script.
