Can I set env vars for dependencies in setup-tools?

Question

Is it possible to set env vars to be used by dependencies set in the setup.py file of a package?

Specifically; the lxml package is a dependency of one of my packages. To help ease deployment I want to set STATIC_DEPS=true and some CFLAGS for lxml in the setup.py file for my package, so that our users can just easy_install my-package without any install issues.

Answer 1

Isn't that the default behaviour? Just

export STATIC_DEPS=true; easy_install lxml
