You can't even get Rust of Go to run easily on a slightly older machine (e.g. try it on a OS X Yosemite machine) because all the compatibility issues. That's not even getting to all the "online" dependencies. This are two of the worst language ecosystems in this regard (I don't know anything that would be worse actually.)

No such problems with complex C compiler packages.

Hopefully the gcc Rust project can mitigate some of the issues for Rust (since everyone wants to rust-ify long standing projects these days and hence breaking backwards compatibility of the respective packages just to be "hip & trendy")
