Note : the answer now given by sage is another (valid) solution, as acceptable as the one expected, to the problem. This doctests the longest.path() method of (possibly directed) graphs. The doc hints at the use of LP methods to solve it. Since these LP methods often use random generation, not getting the same answer when two distincts solutions exists is not necessarily a problem, ab least in my eyes.
So this might be a glitch, even if it's not a fluke. Hence another question : shouldn't the doctests either avoid multiple solutions problem if multiple solutions exist, or test against the whole solution (set of all acceptable solution, if it can be finitely expressed) ?
