pybitmessage fails to detect PyQt4.QtCore module due to sip error

[ng0]

Hi,

I can't provide full patches yet, so these file-inserts
are to show where I'm at now.

The problem I run into is even though the new
package "python2-pyqt-4" in gnu/packages/qt.scm
builds, I get a failing detection in python ide

and of course also in execution of the

So at this moment, or at least for today, I'm stuck
and new input would be very welcome.

These are the packages:
