I cannot seem to find much out about why this happens or how to get around it. That was where the -m32 settings came from; a shot in the dark to see if it would work. So, the problem is in configuration.

OK, looks like I had checked this a while back, and the only workaround I found that works is a bit ugly.

The SIP/PyQt checking code in cmake tries to run python, as found by cmake, and import SIP/PyQt.  It's supposed to accept a compound command, so it should be possible to set PYTHON_EXECUTABLE to "arch -i386 /usr/bin/python2.6", but I could not get that to work.

So, ugly hack:

sudo cat >/usr/local/bin/python32 <<EOF
#!/bin/sh
exec arch -i386 /usr/bin/python2.6 \${1+"\$@"}
EOF

sudo chmod +x /usr/local/bin/python32


Then configure Qgis with 

-D PYTHON_EXECUTABLE=/usr/local/bin/python32
