Hi Ben,

welcome back!  gm2 is now in the gcc git, a minimal clone and build
could be (depending upon your system):

$ git clone git://gcc.gnu.org/git/gcc.git gcc-git

If you are behind a firewall that does not allow the git protocol
through, you can replace git:// with https://.

Building
========

$ cd gcc-git
$ mkdir build
$ cd build
$ ../configure --enable-languages=m2 --prefix=$HOME/opt
$ make -j 30
$ make install
$ make check-m2 -j 30   # testsuite running is optional (dejagnu needs
                        # to be installed)

Running the compiler
====================

$ export PATH=$HOME/opt/bin:$PATH
$ gm2 hello.mod
$ export LD_LIBRARY_PATH=$HOME/opt/lib64:$LD_LIBRARY_PATH
$ ./a.out

hope this helps,

regards,
Gaius
