yes

I put the the "Cython-0.11.1" into the PATH and don't modify the
PYTHONPATH

the INSTALL.txt say: On unix, *also* put the bin directory on your PATH

but I think I found the reason I have to set the PYTHONPATH to this
directory *and* setup the PATH. I understand *also* as something like "or"

but now the following error happen:


> PYTHONPATH=~/ext/x86_64-suse-linux/thread/bin/Cython-0.11.1/
PATH=$PATH:~/ext/x86_64-suse-linux/thread/bin/Cython-0.11.1/
python ./setup.py build_ext --inplace
Traceback (most recent call last):
  File "./setup.py", line 3, in <module>
    from Cython.Distutils import build_ext
 
File "/home/dev1usr/ext/x86_64-suse-linux/thread/bin/Cython-0.11.1/Cython/__init__.py",
line 2, in <module>
    from Shadow import *
ImportError: No module named Shadow

SuSE 10.3, I have compiled python on my own and install it in:
~/ext/x86_64-suse-linux/thread
