Hi Bram,
After installing vim7.3 on a ubuntu system, I had again the problem that
import did not work for .so libraries in lib-dynload. I found that
sys.path was initialized with "/usr/..." instead of "/usr/local/...". On
ubuntu (and probably on other linux distros as well) python3 is
installed in /usr/local while python2 is installed in /usr.
The attached patch calls Py_SetPythonHome with PYTHON3_PREFIX defined by
configure.
This solves the problem.
regards, Roland
