rustpkg: install from remote repository not working

[pascalj]

Installing a package from a remote repository from Github gives me:

$ rustpkg install git://github.com/brson/rust-sdl.git    
rust: task failed at 'Package git:/github.com/brson/rust-sdl.git not found in any of the following workspaces: [.]', /Users/pascal/git/rust/src/librustpkg/workspace.rs:24

Note the missing / in the URL. The same is happening if I omit the git:// part. Tested with 3290110. The people on #rust noted that rustpkg is not usable today but encouraged me to file a bug so that it doesn't get lost.

Thanks for the bug report! This is actually covered by a more general bug, #5679, so I'm closing this one as a duplicate. Keep them coming, though!
