Should I Uninstall MacPorts to Reinstall?

[Susana]

Hi,

I'm a new user, and I think this is how I ask a question.  I am downloading
the digiKam photo application, and to do that, I was required to download
Xcode and Macports.  I downloaded Xcode 3.0 and then I downloaded Macports.
 In the terminal, it said:

"Warning: The installed version of Xcode (3.0) is known to cause problems.
 Version 3.1.4 or later is recommended on Mac OS X 10.5."


So now I have downloaded 3.1.4 Xcode.  Do I need to reinstall Macports
because of the new Xcode version?  I am worried that during the Macports
installation, it said that certain things being downloaded were not found
(written in the Terminal window), and I wonder if that's because I had an
older version of Xcode that it says causes problems.  But I'm worried that
if I uninstall Macports, I might mess something up, especially since
MacPorts website says uninstalling can be a drastic action.  Honestly, I
don't really know what Macports is at the moment (should look into that).
 I just downloaded because of digiKam.  I didn't have it before, so how can
uninstalling be drastic?  Does it have to do with the software I download
using MacPorts?  I'd assume since I haven't made the final step of
downloading digiKam, it would be okay to uninstlal since I haven't used
MacPorts.  I've opened/installed it but have not used it to download
software.

And does Xcode come with your Apple computer?  MacPorts does not?


Thank you!
Su
