rust/configure
Erick Tryzelaar 5f066e06b9 Update to libuv commit 3ca382.
This patch changes libuv's gyp build system to
make it's own makefiles. To generate them for rust,
run these commands. They requires python 2.x to
work:

$ mkdir -p src/rt/libuv/build
$ svn co http://gyp.googlecode.com/svn src/rt/libuv/build/gyp
$ ./etc/src/gyp_uv
