Comment # 34 on bug 110795 from Andrew Shark

@Tomas, it is strange that it did not asked a password after "Creating local
repository..." which is before "Installing OpenGL PRO...". Probably you already
had a previous version of repository (it happens if you try to install it with
official installer script first).
Try to force remove it (script provided as another attachment) and then re-run
my installer script.
