The scripts/rust_is_available.sh change looks correct to me, although I couldn't
get scripts/rust_is_available_test.py to run on NixOS. 

Looks like it filtered out PATH but uses /usr/bin/env to find python binary? For
obvious reasons that will only work if python is located /usr/bin/python.

Best,
Gary
