This probably could be named a bit better as I confuse pkg_env with the
package.env file.

if (not env.has_key(var)):

This is the same as not var in env
>>> dict = { "foo":"bar", "foo2":"bar2" }
>>> "foo" in dict
True
>>> "foo3" in dict
False

for p in pkgs:

Although the current functions are not documented, it would help if we
documented all new functions using pydoc:
http://www.python.org/dev/peps/pep-0287/

If it works, I am fine with you committing it. Should probably get a
couple of other fixes in there at the same time too for a new release.
