[issue7219] Unhelpful error message when a distutils package install fails due to a permissions error

[Éric Araujo]

Éric Araujo <merwok at netwok.org> added the comment:

An IOError is raised but file_util._copy_file_contents only produces the helpful message “could not create '<file>': <error>” when catching os.error.

Catching both classes is easy. We’d need a regression test first, and before that, agreement from Tarek that such a change would be okay.

I wonder what is this mysterious None that we get as a result.
