Fresh clone of cargo fails to build

[ollie]

Hello,

I reinstalled Rust today (rustc 0.12.0-pre (f7ec95efb 2014-09-03 02:40:59 +0000) and also wanted to reinstall cargo but it failed. I'm not sure it's related to Rust change or Cargo change (or something wrong here). I'll happily provide more info if you tell me what/how.

Thank you,
Ollie

[alexcrichton]

I'm sadly unable to reproduce this, what SHA of cargo were you building?

[ollie]

I did it today so it's the latest 3139954ceda3c62e311fe1e4956f554724195fea.

[ollie]

I'll try rebuilding rust and cargo now just to make sure.

[ollie]

Hm, still fails with the same error

Ah it seems that you're compiling with rust master, not nightly. It looks like @suhr's got this handled in #505 as well.

[ollie]

Thanks.
