After building py2cairo-1.10.0 with the following:
> export PYTHON=/usr/bin/python2.6
> python2.6 ./waf configure --prefix=$HOME
> python2.6 ./waf build
> python2.6 ./waf install

I get the following errors after importing cairo with the following:
cd $HOME/pycairo/lib/python2.6/site-packages/cairo
>> import cairo
>> ImportError: ./cairo.so: undefined symbol:

ldd -r cairo.so gives:

I'm using the following version of Python and Cairo:

pkg-config --modversion cairo:

python --version
Python 2.6.4

I have rebuild Cairo (needed to rebuild pixman, glib and libpng for this)
but I keep ending up with the same problem and I can't find the problem (or
better; the solution).

Thanks in advance!
