[PyQt] Installing PyQt4 on OS X 10.10

I am trying to get an ocean turbulence model (www.gotm.net<http://www.gotm.net>) running on my Mac.  The GUI is specified as requiring Qt4 and PyQt4, so I downloaded the last release of Qt4 from the archive

qt-opensource-mac-4.8.6-1.dmg<http://download.qt.io/archive/qt/4.8/4.8.6/qt-opensource-mac-4.8.6-1.dmg>

Which I ran as a normal Mac installer and it reported a successful installation.

I also downloaded the last PyQt4 release from archive http://www.riverbankcomputing.com/software/pyqt/download

PyQt-mac-gpl-4.11.3.tar.gz<http://sourceforge.net/projects/pyqt/files/PyQt4/PyQt-4.11.3/PyQt-mac-gpl-4.11.3.tar.gz>

When I start the installation with the --verbose flag set, I get:

Air-2010:PyQt-mac-gpl-4.11.3 brianscannell$ python configure-ng.py --verbose

Error: Failed to determine the detail of your Qt installation. Try again using

the --verbose flag to see more detail about the problem.


I am not a developer, so in all honesty, I don't understand what the message is telling me, but it seems to have found the Qt4.8 but is throwing a hissy fit about ‘-Xarch_x86_64’ in the command line.  Clearly it is something about the hardware architecture, but after that I'm at a loss.

Any suggestions on what I need to do to get PyQt installing?

Thanks, Brian
