Been trying to get around this error for a while now. I did some heavy digging and some sources said it involves having a conflicting version of Qt already on board the system. Since I'd been fooling around with Qt installations for a while, I did the next quickest thing and deleted my Ubuntu partition for a fresh installation. Did the first round of updates on SPM, restarted and attempted the Qt installation again and, lo and behold, error is back. There's no reason to suspect I have a Qt version lying around anymore so now I'm completely out of ideas.

Error happens during "sudo make". "sudo ./configure" works quickly and properly. I am following these instructions http://qt.nokia.com/doc/4.6/install-x11.html.
