Comment 7 for bug 377584

So, since there is still no clear test case here, I tried to download pygtk sources. Upstream configure is not built on Ubuntu. I ran autoreconf, and diff'ed the original and newly produced configure. The definition of PYTHON_PREFIX and PYTHON_EXEC_PREFIX didn't change. So what's the actual error here, which problem does this try to solve? Or is pygtk a bad test case? If it only happens with some projects, please tell which project it can be tested with.
