The way to do this is to setup an environment that makes it easy to
fetch new versions of McCLIM (and ideally the dependency libraries)
from CVS, since McCLIM releases aren't done that often, so you'll miss
out on many improvements, bugfixes and compatibility fixes if you only
run releases. One way to do so is to use clbuild
(http://common-lisp.net/project/clbuild/), which is probably the
simplest way to fetch and update bleeding-edge versions of certain
Lisp software. Alternatively, a common approach is to use ASDF-Install
to install McCLIM, and subsequently checking out McCLIM from CVS with
the usual command:

cvs -z3 -d :pserver:anonymous:anonymous at common-lisp.net:/project/mcclim/cvsroot co mcclim

Note that currently it is also necessary to get the Flexichain library
from CVS:

cvs -z3 -d :pserver:anonymous:anonymous at common-lisp.net:/project/flexichain/cvsroot co flexichain

Flexichain doesn't normally change a lot, so in most cases the
ASDF-Installable version is sufficient, but current CVS McCLIM depends
on an unreleased Flexichain.

Your use of CMUCL may cause problems. CMUCL is perfectly capable of
running McCLIM, and as it has both (green) threads and a fast
compiler, it is probably the second-best choice after SBCL. However,
CMUCL used to have some problems with forward-defined classes, which
McCLIM uses in a few places. If I recall correctly, it was usually
possible to get McCLIM to load by manually copying and pasting class
definitions to the REPL when the errors happen during loading, after
which it would load and run perfectly. This bug may have been fixed in
CMUCL since I last tried it, however.
