Comment(by ryandesign@…):

 Upgrading everything is safest in terms of making sure dependencies aren't
 suddenly broken, though as you say there is always the danger of new
 undiscovered bugs. If you're aware of what depends on what, you can be
 selective about what you upgrade. But certainly all your bundled php5
 extensions must be the same version number as php5 itself. How do you know
 which php5 extensions are bundled and which aren't? Probably easiest is
 just looking at the version number -- if it's 5.3.something then it's
 probably bundled and should be upgraded to match the version of php5. You
 can also look in the extensions' portfiles themselves (using e.g. "port
 cat php5-whatever") -- bundled extensions have the word "bundled" at the
 end of the line that begins with "php5extension.setup".
