Hi

the invalid python path suggest there is some clash with the
libraries/modules. Please make sure to completely clean up your qgis
installation and try again. This could be a result of some old c++
plugins in the (prefix)/lib/qgis directory or something similar - have
you done any updates of Qt4, PyQt4 or sip recently?
