No.  But it will run fine on a VM with closures.

The only package needed is the NewCompiler, and only if you decide to
run with the WriteBarrier option enabled.

The only other package strongly recommended is OSProcess, but only if
you want to run the test-suite.

The 3.10-4 Linux VM is not a closure VM, but Magma runs fine with the Pharo VM.
