I can´t compile rust-1.29.2

[padawan]

Hello, i´m recently installed Funtoo linux following the install guide of the official page of Funtoo. (Sorry if my english it´s bad, i´m spanish speaker)

Ok, my problem it´s the following: when i execute the command: 

emerge -auDN @world

It gives me the following errors when compiling rust-1.29.2:

failed to parse TOML configuration '/var/tmp/portage/dev-lang/rust-1.29.2/work/rustc-1.29.2-src/config.toml': expected a table key, found a right bracket at line 33.

And here is the build.log of the compilation:
