I appears that in a new version the Julia library added a definition that
is ambiguous with a definition in your code. Unfortunately this is always
possible with multiple dispatch systems. The solution is as described in
the error message, if you are sure that the two definitions are correct.
IIUC this declaration is not added automatically as that could hide some
types of real errors. For more information
see http://docs.julialang.org/en/release-0.3/manual/methods/#method-ambiguities
