[16:18] <chrisccoulson> brson, do rustc and cargo need to be updated together? (someone updated rustc in ubuntu to 1.16 last week, with cargo at 0.16 and I'm wondering if that's the cause of https://launchpadlibrarian.net/312038221/buildlog_ubuntu-zesty-i386.firefox-trunk_55.0~a1~hg20170323r349151-0ubuntu1_BUILDING.txt.gz)
[16:18] <chrisccoulson> error[E0523]: found two different crates with name `std` that are not distinguished by differing `-C metadata`. This will result in symbol conflicts between the two.

[16:18] <chrisccoulson>    | ^^^^^^^^^^^^^^^^^^^^^^^^
[16:58] <brson> chrisccoulson: yes they should be paired
[16:59] <brson> chrisccoulson: i actually mean to send out an email about this
[16:59] <brson> the build process for rust is changing so the entire 'distribution' is built from the rust-lang/rust sourc, including cargo
[16:59] <brson> because they are both part of one product
[16:59] <brson> and it's easier
[16:59] <chrisccoulson> ah, that sounds better :)
[16:59] <brson> this is going to affect packagers that are mostly treating them as separate products today
