rustup 0.6.1 is out. Update with rustup self update.
This fixes a segfault during installation on OS X 10.10+, and makes the rustup component remove command work correctly.
Fixed rust-src packages are still not available on nightly. It looks to me like they should be available Thursday, though there is still more testing to do to verify things work.
0.6.1
