So I followed Kevin's suggestion and installed MinGW along with gcc
and autoconf tools needed by hs-plugins. Then it failed with the
$ cabal install --enable-documentation plugins

Any clues? Should I try to use latest source tree? I am really
interested in the plugins approach, rather than the interpreter
approach. What I am trying to achieve is a system similar to Yi as
presented in Don Stewart's paper
(http://www.cse.unsw.edu.au/~dons/papers/yi.pdf), but much simpler, of
course. The system would load modules as found in some known location,
run tests found here before really accepting them, then use them, with
the possibility of replacing those modules when a newer version is
found. The idea is to provide a self-tested and continuously running
system for development, something that might be reminiscent of
Smalltalk although I never programmed in Smalltalk.
Thanks in advance for advises,
