You can find out what files it installs by using "port contents  
ghostscript". It looks like it's these files:

   /private/etc/cups/pstoraster.convs
   /usr/libexec/cups/filter/pstopxl
   /usr/libexec/cups/filter/pstoraster
   /usr/share/cups/model/pxlcolor.ppd
   /usr/share/cups/model/pxlmono.ppd

If the port modified any Apple-provided files, then no. But, no port  
should be modifying any Apple-provided files. They may merely (as per  
the message) be installing new files outside the MacPorts prefix. And  
if so, then yes, "port uninstall" will uninstall those files also.

Probably installs ghostscript without support for CUPS (the Common  
Unix Printing Solution). "port variants ghostscript" says so. Not  
sure what exactly that entails for ghostscript. But it sounds like it  
might entail not installing things outside the MacPorts prefix. Which  
would be good, especially if you do not plan to use the CUPS features  
of ghostscript, whatever those might be. (Perhaps the maintainer can  
enlighten us.)
