I find it really interesting that Rust itself requires all these languages to compile:

    g++ 4.4 or clang++ 3.x
    python 2.6 or later
    perl 5.0 or later
Does anyone know why that is?


The perl dependency is from LLVM. Rust uses Python for utility scripts, "Just Because."

Also, you left rustc off the list of languages required to compile rust. :-) It's self-hosted.


Looks like mostly building scripts (documentation, tests ..)

Guess they expect all platforms to have Perl and Python these days..
