Really hacky example of how to compile a CC file using rustpkg. Rustpkg needs heaps of changes before I would even suggest doing anything like this.

rustpkg_w_lib.rs

// this is a horrible way to do it, but it would work

#[pkg(id = "com.frozencow.some_binding",
      vers = "0.1.1")];
#[pkg_crate(file = "src/some_binding.rc")]; // the binding has FFI stuff that links to -lsome_lib

// this would be wrapped by default..
fn cc(path: &Path) {
	run::run_program(~"cc", ~[~"-shared", ~"-o", rustpkg::build_dir().push(~"lib").push(~"some_lib.so").to_str(), path.to_str()]);
}

#[pkg_do(build)]
fn build() {
	cc(&Path("some_lib.c"));
}
