Your configured editor (probably vi) will pop up with an already loaded file.

Search for the lines containing / and /usr/bin (lines like %dir %attr(0755, root, root) "/"), and remove them. They are starting in about line 340.
(I removed the line with /usr as well.)

Save end exit.
Answer yes. It will then tell you the location of the fixed rpm.
