Thanks.

AFAIK, mps is not packaged by Debian.

For building it locally, possibly the easiest route is to clone

https://github.com/Ravenbrook/mps.git

(which was updated just today, BTW), compile with


cd code
cc -O2 -c mps.c
ar rvs libmps.a mps.o

Then config the Emacs build with

configure CPPFLAGS=-I/path/to/mps/includedirectory
LDFLAGS=-L/path/to/mps/codedirectory --with-mps=yes <... rest of
configure options..>

This can have a variation for compiling&using the debug version of mps.

The above is not tested with the current state of mps/emacs. I can try
later and add those instructions to README-IGC.

Whe should decide if we direct users towards the optimized build (better
engagement and real-case experience) or to the debug build (better bug
reports but unusably slow in my experience).
