For a long time, I've been having a problem upgrading 'icu'. There seems to be a conflict with KDE :

'icu' provides "international components for Unicode" : whyever is that simple stuff running into this problem ? Any suggestions welcome. -- ========================,,============================================ SUPPORT ___________//___, Philip Webb ELECTRIC /] [] [] [] [] []| Cities Centre, University of Toronto TRANSIT `-O----------O---' purslowatchassdotutorontodotca
