Done. Thanks for helping.

You contacted me on IRC, but on my workstation, wrong account. Add me as comaintainer yes

Updated mkdir flag and version.

The best way to build this package is to use your existing Rust installation but PKGBUILDs aren't supposed to modify other files in $HOME (hence the temporary RUSTUP_HOME situation).

you need to add -p to "mkdir nightly" command. At the second build, it fails with "directory already exists".
