See this comment, but the general take-away is we need newer version of pip, which ignores that error. I've just tried it and it works with pip 8.1.2. @hhorak is update of pip possible in scl? @mnagy have you tried other versions/images, does it apply there as well?

[mnagy]

@soltysh nice, thanks for finding that! Yes, I tried and they work well. And actually, I realized later that this error message does not fail building the image, so it actually works ok. Would be nice to get rid of it, however.

[soltysh]

👍 for getting rid of it.

We'll track pip update in this BZ: https://bugzilla.redhat.com/show_bug.cgi?id=1344674
