If you have a Rakefile or a mkrf_config in the ext directory, it
should use those instead of an extconf.

Just add mkrf as a dependency like you would with other gems.

There's an example in the Pickaxe, and one here
I can't speak to quoting pathnames. I'd say mkrf is probably a better
starting point if _any_ hacking is to be done. I've quarantined the
part of my brain that understood mkmf for fear the disease would
spread. It isn't as widely used though, so there may be things
missing. Please _do_ file bug reports if that's the case.

Probably, but honestly at this point I end up going to the source or
to my other gems.
