Do you mean installing the MacPorts xorg port, or something else?

Based on what you've written, I don't believe that uninstalling and reinstalling MacPorts would help, or at least would not be the most efficient way to solve the problem.

Not having had Xcode or the command line tools installed at the time you installed MacPorts is not a problem. It could just cause some ports to fail to build. That can be remedied by installing Xcode or the command line tools and trying to install the affected port again.

Googling this warning led me to this page:

Of course that would apply only to XQuartz. When installing xauth with MacPorts, I presume you would instead use:
