I didn't know that! :)

Yes, I understood that. I noticed that you all put effort into this.
And I certainly do not want to let that go unnoticed.

As a matter of fact, however, we have currently more than eight ways 
to build a Squeak/Pharo VM, and for _everyone_ using either of them,
there is a high effort learning another one, and one as to make
a decision where to put ones effort, just like you said, where to
invest ones time. 
  Basically, people like (but not limited to) Eliot or Tim have to
decide whether to improve the VM itself or invest time learning a
different build system from what they are using now, notwithstanding
that a new one even might be better/more efficient/cleaner etc….

Long story short, _I_ think there are too many ways to build a VM
for a newbee to decide which to use.
