The name of the runtime alone isn't that useful. You'd probably want the
version of Mono as well.

Probably the best way to do this is to test if `basedir typeof
(object).Assembly.Location`/mcs.exe is there (using c# + bash :-), and
if it is to execute that with --version. (I guess you need to test for
gmcs.exe too, since that is what will be there for 2.0...)

If you want a simpler test, being able to load Mono.Posix via reflection
would be a pretty good one. Much better than depending on an internal
type like MonoType...
