I've sucessfully emrged soya (ver. 0.9.2) however when I run ./racing.py i get this message:

Traceback (most recent call last):
  File "./racing.py", line 20, in ?
    import soya
  File "/usr/lib/python2.4/site-packages/soya/__init__.py", line 26, in ?
    from soya._soya import *
ImportError: /usr/lib/python2.4/site-packages/soya/_soya.so: undefined symbol: CalModel_Destroy

what's wrong with that?
