Hi, this one is "funny". setuptools uses python's os.uname() to check which arch it is running on, and where the temp-build-path is. This fails nicely on machines with 64bit-kernel and 32bit-userland (at least amd64, as it has x86_86 in uname, as the kernel is for x86_64).
In this particular bug, it's not 64 vs 32 bit, but i686 vs i486, quoting the build-log: > g++ -pthread -shared -Wl,-Bsymbolic-functions -g -O2 build/temp.linux-i686-2.6/src/wrapper/wrap_cl.o build/temp.linux-i686-2.6/src/wrapper/wrap_cl_part_1.o build/temp.linux-i686-2.6/src/wrapper/wrap_cl_part_2.o build/temp.linux-i686-2.6/src/wrapper/wrap_constants.o -lboost_python-py26 -lOpenCL -o build/lib.linux-i686-2.6/pyopencl/_cl.so > PYTHONPATH=../build/lib.linux-i486-2.6/ /usr/bin/make -C doc html the stuff is built in build/lib.linux-i686-2.6/, but PYTHONPATH is set to build/lib.linux-i486-2.6/. This is done in debian/rules: PYTHONPATH=../build/lib.$(DEB_BUILD_ARCH_OS)-$(DEB_BUILD_GNU_CPU)-$(firstword $(PYVERS)) $(DEB_BUILD_GNU_CPU) is wrong here, as is expands correctly to i486 (even on amd64 kernel with a i386 chroot).

I fear we have to "parse" `uname -m` here, to fix that issue and match setuptools' algorithm.
