You're misinformed.
- Scheme is a programming language, not a piece of software.
- Free implementations of Scheme exist in Debian, e.g. Guile.
- lsh does not use a Scheme interpreter at run-time.
The issue is:
- The build process of lsh currently uses scripts that use "scsh", a Scheme
interpreter with support for writing shell scripts.
- "scsh" is not free software at the moment.
This issue is minor for the following reasons:
- The "scsh" copyright holders have been asked to free it. They are willing
to do so, but currently do not have the time to handle the paperwork
involved. Thus, "scsh" can be expected to become free.
- The "scsh" scripts used in the build process are fairly small.
Should "scsh" not be freed by the time lsh is sufficiently stable to be
part of Debian, they can be adapted to work with a free Scheme
implementation without to much effort, or rewritten in a different
scripting language (they do text processing; Perl or Python would be good
candidates).
