Subject: Re: Rake: Making "cleanup" task

That's looking like a cool solution. What is that
at_exit thing, btw? Is that a standard part of rake
I should know about?

Note:
We've gotten as far as building Ruby on solaris,
but seem to be missing the libraries. I'll looking
to find a way to give the installation instructions
back to the community, when I've finished figuring
out the details.

Since the libraries are missing, the rake install
failed...but I look forward to getting the issues
resolved soon. Rake is the reason I've begun taking
a very serious look at Ruby.
