OK, I am having a problem building the howto module with CMake.

Here is the output of all the steps:

address@hidden build]$ cmake ../

Now in python I try:

address@hidden build]$ python
Python 2.7.1 (r271:86832, Apr 12 2011, 16:15:16)
[GCC 4.6.0 20110331 (Red Hat 4.6.0-2)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import howto
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/lib64/python2.7/site-packages/howto/__init__.py",
line 45, in <module>
    from howto_swig import *
ImportError: No module named howto_swig

The module howto_swig is missing....
Any thoughts?
