@alexcrichton here are the two most recent Bitrig snapshots.  As usual, please upload the snapshots to the snapshot server:

https://github.com/dhuseby/rust-cross-bitrig/blob/master/snapshots/rust-stage0-2015-03-25-a923278-bitrig-x86_64-e56c400a04bca7b52ab54e0780484bb68fa449c2.tar.bz2
https://github.com/dhuseby/rust-cross-bitrig/blob/master/snapshots/rust-stage0-2015-03-27-5520801-bitrig-x86_64-55a69b0ae5481ccda54c2fcfc54025a0945c4f57.tar.bz2

BTW, I was just able to get the Bitrig Rust build to pass "make check" so I'll submit a PR once this lands to fix the tests and get the Bitrig buildbot to finally complete a build.  That will hopefully end this nonsense of hand building and uploading snapshots. :+1:
