well this is due to the fakt that mdk 10 probably used a different gcc then 10.1 so this does not work...
have you tryed the wxGTK and wxGTK-devel version 2.4.2 which are on our dl page? those are genenric once and should work on any mdk...
only thing I dont know is if the amule-2.0.2 is linked aginst wx-2.6 then this would NOT work,
you can write maybe an PM to wardevil and ask him....what wxGTK he used, that would probably be the best and fastest way...
or compile it yourself
