@DarkSun: use the latest python-sip-pyqt4 4.19.15, do not downgrade it.

There are two remaining problems with this python-pyqt4 package:

1. This package PKGBUILD must be changed to python-sip-pyqt4 and python2-sip-pyqt4 instead of python-sip and python2-sip, because the latter do not build the necessary PyQt4 module, so if you do not have the former installed, you will get:

   AttributeError: 'module' object has no attribute 'QWidget'

@buzo, can you change the dependencies here?

1. For Python 2, python2-sip-pyqt4 is out-of-date (4.19.13) so its PKGBUILD must be edited manually to update to 4.19.15. Really, python2-sip-pyqt4 should be deleted and python-sip-pyqt4 should be a merged package that builds for both python 2 and 3.

@alexei python-sip-pyqt4 is updated to 4.19.15, Is it still neccesary to change the python-sip-pyqt4's version to 4.19.14?

Did you read the comments before posting? There is a workaround there.

Sorry for my post @alexei, its ok now.

Same as @JohnRobson

@alexei Thank you for the clear instructions, it installed okay!

Error making: pyqt4 (pyqt4-common python2-pyqt4)

@mark: on line 14, change python-sip python2-sip dependencies to python-sip-pyqt4 python2-sip-pyqt4. EDIT: and remove the former packages if you have them installed.

The error you cite just tells you to install pyqt4-common from AUR, which is a dependency of this package. If you use yaourt (or similar) it fetches dependencies automatically, otherwise you have to install deps manually.

I'm still having trouble installing this.

I've added the temporary workaround after configure commands, but I didn't quite get where the rest of the changes should be made. Even though it should build but not work with just this hotfix?
