BzrGtk, import error

[ITSec_Mike]

Hi all

I successfully insalled cairo, pycairo, and bzr-gtk on SUSE 9.3.
By running bzr visualize I get the following error:

bzr visualize
bzr: ERROR: exceptions.ImportError: /usr/lib/python2.4/site-packages/cairo/_cairo.so: undefined symbol: cairo_ps_surface_create
