nix and nixpkgs allow this isolation on-top off linux, freebsd, OS X and
theoretically also cygwin (not sure how good cygwin is supported at the
moment).

http://nixos.org/nix/
http://nixos.org/nixpkgs/

From nixos.org:
Nix is a purely functional package manager. This means that it can
ensure that an upgrade to one package cannot break others, that you can
always roll back to previous version, that multiple versions of a
package can coexist on the same system, and much more.

Nixpkgs is a large collection of packages that can be installed with the
Nix package manager.

Nice! Looking forward to that.

If you have any questions about nix/nixpkgs/nixos, especially about the
way python packages are packaged, please let me know. Also, it's not set
in stone.

Personally, I'd love to see hydra.python.org providing builds of all
pypi packages and would be happy to help. Also including Domen and Rok
for whome I assume the same.

You might have other tools that are better suited for you.
