Should be as easy as...
$ git clone https://github.com/OpenSmalltalk/opensmalltalk-vm.git
$ cd opensmalltalk-vm/build.linux..../pharo.cog.spur/build.debug/
$ ./mvm
...and look for binaries in "products" directory.

Maybe there are times when your installed autotools versions conflicts
(IIUC Eliot sometimes has problems on newer Linux versions).
If you hit such problems, one path forward may be to leverage Luke's work
to produce a Nix build, which "should" be entirely reproducible on anyone's
@Luke, could you refresh me on how to kick off a Nix Pharo VM build on a
non-NixOS platform?

Building the VM hasn't been my issue (it's been working nicely for me in a
variety of Linux environments), building the VMMaker image has been the
problem.  A while back I was using Eliot's buildsqueaktrunkvmmakerimage.sh
script but that stopped working for me (I think the last time it
successfully ran for me was pre-github migration).  Last week I tried to
manually install the VMMaker package in Squeak and got an error, this week
I tried to install it via Pharo and got a different error.  So rather than
try to debug any of these approaches which may be obsolete, I was really
trying to ask for pointers to the currently recommended method to build a
VMMaker image.
