[Zope] Error with installing zope 2.7.2

[Martin Koekenberg]

Hello,

I did a new try to install Zope 2.7.2. But i'm getting a error with I can't explain.

TypeError: unsupported operand type(s) for +: 'NoneType' and 'str'
(This is the same error I get whem I want to install PIL.)

This Is the way I installed Zope

./configure --prefix=/usr/local/zope/2.7.2
Make 
Then I get the following error line :

running build_ext
Traceback (most recent call last):
  File "/usr/local/zope/Zope-2.7.2-0/setup.py", line 1091, in ?
    distclass=ZopeDistribution,

    cpp = cc + " -E"           # not always

make: *** [build] Error 1                                               

Where do I have to serach for the solution, Is it Zope, Python or a corrupted library ???
Whon can Help me ?

Thanks,
