You might be one of the very few lucky people out there who’s got a working installation of MacPorts running dating back to your Leopard (10.5) environment – but for the remainder of us (including everyone on the Meeho!™ team), upgrading to Snow Leopard makes MacPorts not work properly.

Here is an example of an error we got:

Error: Unable to open port: can't read "build.cmd": Failed to locate 'make' in path: '/opt/local/bin:/opt/local/sbin:/bin:/sbin:/usr/bin:/usr/sbin' or at its MacPorts configuration time location, did you move it?

If you are experiencing compile errors of nearly any kind, having yourself cursing and swearing trying to get your darn MacPorts to work again, do not worry: practically, no matter which error(s) you might receive, the solution is for you to do a clean install of MacPorts – it worked for all of us.

To get it all right again, please follow the Migration guide on the MacPorts web site: http://trac.macports.org/wiki/Migration
