[PySide] Can't build with -Dshiboken_SUFFIX

[todd rme]

I am trying to do a parallel install of pyside and shiboken on python
2 and python 3 under linux.  I tried setting the cmake variable
-Dshiboken_SUFFIX="-python3.2".  However, it gives the following error
when I do so:

Linking CXX executable shiboken-python3.2
[ 96%] Built target shiboken
[ 98%] Running generator for 'shiboken'...
/bin/sh: /home/abuild/rpmbuild/BUILD/shiboken-1.1.1/build/generator/shiboken:
No such file or directory
make[2]: *** [shibokenmodule/shiboken/shiboken_module_wrapper.cpp] Error 127
make[1]: *** [shibokenmodule/CMakeFiles/shibokenmodule.dir/all] Error 2
make: *** [all] Error 2
error: Bad exit status from /var/tmp/rpm-tmp.D3ll4U (%build)

Is there any way to fix this, or a better way to achieve a parallel
installation?
