[BioPython] Biopython installation syntax error

[Anthony Amend]

Hi,

I'm trying to install biopython 1.49 on a mac running OSX 10.4.  I've  
installed numpy 1.2.1 and when I log on as root and try to install  
biopython I get the following error:

File "/System/Library/Frameworks/Python.framework/Versions/2.3/lib/ 
python2.3/site-packages/numpy/lib/arrayterator.py", line 89
     slice_ = tuple(slice(*t) for t in zip(
                                ^
SyntaxError: invalid syntax

I figured it had something to do with the numpy installation, so I  
went back and installed numpy 1.1.1, but got the same error message  
when I tried to install biopython again.

I'm a VERY new unix/python user, so if you have any insight please  
dumb down your answers accordingly.

Many thanks for your help

Anthony
