This looks great!

I have one question about:
0002-pth-file-with-deps-only-current-package-s-scripts-no.patch

If you remove a package does
$out/lib/${python.libPrefix}/site-packages/"{easy-install.pth,${name}.pth}
get left behind?

My understanding of Nix is still a little hazy, but I wonder if
${python.libPrefix}/site-packages should be managed by Nix (maybe it
is already?). Every time a new python package is installed a new
output for site-packages could be created in the store which contains
the relevant .pth files for all the installed modules.

Perhaps I have misunderstood .. is that already taken care of?

Cheers,
Cillian
