I have a mac server and I have both FINK and macport installation of python/numpy/scipy
I was wondering if having both will affect the other? In terms of memory leaks/unusual results? In case you are wondering why both ? Well I like FINK but macports allows me to have python2.4 which FINK does not provide (yes I needed an old version for a piece of code I have)
I wonder this since I tried to use homebrew once and it complained about the machine having port and FINK (I did not realize that port provided python2.4 so was looking at homebrew but when I realized port did give 2.4 I abandoned it)
In terms of how your Python interpreter works, no: there is no negative effect on having Fink Python as well as MacPorts Python installed on the same machine, just as there is no effect from having multiple installations of Python by anything.
