Pivy problem and some other stuff

[azrael]

Hy Guys

Did anyone manage to install and use Pivy. I'm trying it and cant come
closer to the goal I get the message:
Please set the COIN3DDIR environment variable to your Coin root
directory! ** Aborting **

Familiar to anyone?

And there is anoher question in my mind.
 Is there a way to make a list in python which contains a series of
functions. I did'n try it. Something like:
>>>def a():
>>>  return 1

>>>def b():
>>>   return 2

>>>def c():
>>>   return 3

>>>def d():
>>>   return 4

>>> list=[a(),b(),c(),d()]
>>> list
[1,2,3,4]

I kow that for this kind of stuff this in not neccesarry, but for
other suff it, gets interesting.
