Thanks for the contribution, however this is too platform-specific and I don't have an environment to test it. I would like a more general/flexible way, something like an --ignore option. I'm not merging this at this point.

by the way, platform's distro function is deprecated. in the corresponding ticket, it was proposed to use the package with the same name.

i also remember that such feature was discussed in the pip issue tracker. (and there it belongs.)
