Thanks Levente. Unfortunately it did not work:

Seems like you have to build it yourself. Fortunately it's very easy, since Eliot commits the generated sources to the svn repo. So you can build a CogVM/StackVM without VMMaker. Here is how:
"How to build the Cog Croquet VM on Unix
- Install the tools (gcc, X11-devel, etc (e.g. libpng, libX11 & libxt
source)) 2. Check out the following sources from svn (if you haven't already - if you're reading this in unixbuild its likely you've already got the sources) svn co http://www.squeakvm.org/svn/squeak/branches/Cog/platforms svn co http://www.squeakvm.org/svn/squeak/branches/Cog/src svn co http://www.squeakvm.org/svn/squeak/branches/Cog/unixbuild 3. Open a shell, cd into the unixbuild/bld directory and execute ../../platforms/unix/config/configure CFLAGS="-g -O2 -msse2 -D_GNU_SOURCE -DNDEBUG -DITIMER_HEARTBEAT=1 -DNO_VM_PROFILE=1 -DCOGMTVM=0" LIBS=-lpthread make install prefix=WhereYouWantTheVmToGo 4. At the end of it you'll get a new VM in the path provided via -prefix"
Are there any additional requirements like gcc version, for instance?
I ask because I get errors on the above instructions, on FreeBSD 6.4, running gcc 3.4.6. I can attach configure's output and whatnot, if you're interested.
If configure failed, then please attach the output and continue this thread on the vm-dev list.
I didn't expect the instructions to work, since FreeBSD isn't Linux. So having said that, I've attached the output from configure (which looks fine, to my untrained eye) and the output from make install (which generates errors).
That first error:
In file included from /usr/home/frank/temp/src/vm/gcc3x-cointerp.c:21: /usr/include/malloc.h:3:2: error: #error "<malloc.h> has been replaced by <stdlib.h>"
is probably the culprit, I suppose?

Cog works, but i think you're trying to use the -headless switch, which (is deprecated) and tells the vm to use the X11 display, but with no window. Servers usually don't have X11, so it won't work. You better use -vm-display-null (and -vm-sound-null). Try squeak --help for further useful options (like tuning Cog).
I am trying to use the -headless switch. Good to know it is deprecated. So you happen to have a Cog for linux binary (version 17
- 20), which I could use?
I have one, but I'm not sure it will work on your server. You can find it here: http://leves.web.elte.hu/squeak/cog17.tar.gz . It's built on ubuntu 10.04 and is optimized for core2.
