[MapProxy] Install problem

[DeDuikertjes]

Hi,

I'm trying to get mapproxy up and running on Centos5 (which has python 2.4).

So I installed python 2.6
Created a virtual environment as per install docs.
activated it, and that got indicated on the prompt.
So far so good.
But then:
pip install -r http://bitbucket.org/olt/mapproxy/raw/tip/requirements.txt

Downloading/unpacking MapProxy (from -r
http://bitbucket.org/olt/mapproxy/raw/tip/requirements.txt (line 1))
   Running setup.py egg_info for package MapProxy
     Traceback (most recent call last):
       File "<string>", line 14, in ?
       File "/var/lib/mapproxy/build/MapProxy/setup.py", line 26
         finally:
               ^
     SyntaxError: invalid syntax
     Complete output from command python setup.py egg_info:
     Traceback (most recent call last):

   File "<string>", line 14, in ?

   File "/var/lib/mapproxy/build/MapProxy/setup.py", line 26

     finally:

           ^

SyntaxError: invalid syntax

----------------------------------------
Command python setup.py egg_info failed with error code 1

Please help me resolving this one.
