Whether you use a third-party package manager like MacPorts or Fink is a 
personal decision, of course, and there pros or cons for using either.  
But both MacPorts and Fink are specifically designed *not* to pollute 
your existing system.  They both go to great lengths to install 
everything under their own unique directory subtrees, by default, 
/opt/local for MacPorts and /sw for Fink.  I don't have much recent 
experience with Fink but I do with MacPorts.  Other than a very few and 
documented exceptions, *everything* that MacPorts installs is under that 
/opt/local prefix and there are no conflicts with any Apple-installed 
files so it is really quite trivial to install and remove without fear 
of corrupting your base system.  The whole process is documented here:
