Hi,
I have built a 32 bit version of PyQt on OSX (10.8.2) using Qt5, but it
doesn't
work:

Is there a workaround for this issue?
My setup:
I'm using the git version of qt5 (5.0.x), because there is a bug in
5.0.1
that
prevents 32 bit builds on OSX, with the following config.
./configure -platform macx-clang-32 -nomake docs -nomake examples
-nomake
demos
-nomake tests -nomake webkit -opensource -confirm-license -release
-no-c++11
sip 4.14.4
python configure.py --arch i386
PyQt 4.10 (commercial)
python configure.py --use-arch i386
I had to change qt_macx_spec in configure.py to get it work:
#qt_macx_spec = 'macx-g++'
qt_macx_spec = 'macx-clang-32'
The python version is 2.7 from MacPorts, built as 32 bit.
I have also rebuilt both sip and PyQt4 after doing a "make clean".

You are doing a few things which, at best, are untested.
Can you "import sip"?
yes, that works fine:

4.14.4
There may be an issue building sip with macx-g++ and PyQt with
macx-clang-32.
Even though the spec is macx-g++ sip actually builds using the system cc and
c++, which are symlinks to clang and clang++ so they are both being built by the
clang compiler.
sip-4.14.4$ python configure.py --arch=i386
This is SIP 4.14.4 for Python 2.7.3 on darwin.
The SIP code generator will be installed in
/opt/local/Library/Frameworks/Python.framework/Versions/2.7/bin.
The sip module will be installed in
/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages.
The sip.h header file will be installed in
/opt/local/Library/Frameworks/Python.framework/Versions/2.7/include/python2.7.
The default directory to install .sip files in is
/opt/local/Library/Frameworks/Python.framework/Versions/2.7/share/sip.
The platform/compiler configuration is macx-g++.
MacOS/X binaries will be created for i386.

From previous experience I don't trust MacPorts stuff.
It was all working fine with Qt 4.8.4/PyQt4.9.5, but there is an issue with
4.8.4 on OSX 10.6 that prompted us attempt to move to Qt 5.
What alternatives do I have given that I need a 32 bit build (due to some 3rd
party code that isn't yet 64 bit compatible)?
