Perl 6. That is, after all, the language kit we're ultimately tasked with
shipping. :)
By the time we're in alpha we'll have a working perl compiler, so we're OK.

For now, we can use perl 5.

There's nothing really past what make does. The reason for having our own is:
*) Make isn't everywhere (like windows)
*) Make on various platforms has different syntax (VMS, Windows, and Unix
are all different)
*) Not speaking for anyone else, but I find make's gotten rather creaky
around the edges--after 20+ years presumably we can make things a bit better
*) Having the full power of perl in the build tool should give us a big
boost in utility. (Consider the difference between C macros and Perl source
filters)
*) It'll be really unfamiliar to everyone, which'll stop folks from falling
into old, non-portable habits.
