The situation is actually more basic: src/HOL/Library/Fraction_Field.thy
etc. were moved to a separate session in fc41a5650fb1 and thus you have
a broken IsaFoR still lying around by accident.
What I said about "isabelle imports" is not yet relevant (presently at
10f4a17e5928), because I did not move that far ahead yet -- although I
was pondering when to do it.
(Right now I have the impression that there is an aversion to any kind
of change on the ever changing isabelle-dev repository. We are between
the releases and now is the usual time for bigger reforms. Or are we
already in a state where big things can no longer happen?)
