Author: ryandesign at macports.org
Revision: 32627
Property Name: svn:log

New Property Value:

 * Turn the code that selfupdates the recently-installed MacPorts into a shell function, 'update_macports', so that it can be called from multiple places;
 * Having done that, exit gracefully after calling 'update_macports' if the shell can't be determined, so as to make sure no further attemps to tweak the environment are made;
 * Call 'update_macports' in every single place where we exit the script, as tweaking the environment (whether successfully or not) is orthogonal to updating MacPorts.
