Bug 153279 also notes collisions for all the translations and wx-config. Also missing SONAMEs for 2.4, but I _think_ those are fixed in 2.6 upstream. For translations need to look into patching upstream in 2.8's time, for wx-config and wxwin.m4 will need to think of another solution. eselect or something from that line.

this was fixed with the removal of wxGTK-2.4. future SLOTs have also been fixed.
