hint: remove the old package
(In reply to comment #1) > hint: remove the old package Won't help, you are missing stable keyword for the needed version (2.4.2.4-r3) Reopened.
wxpython-2.4.2.4-r3 is properly slotted and wxpython-2.4.2.4 is not. For the two to co-exist the slotted version (2.4.2.4-r3) must be used. I just resolved this issue here, thanks marienz. PS. I don't know that this is an AMD64 issue per se. If you have not upgraded to the latest version of wxpython-2.4.* on x86 won't you still get bit? Stabilizing wxpython-2.4.2.4-r3 would bring us to the same level as x86.
2.4.2.4-r3 it's stable This is fixed
Some non-Gentoo specific slotting information (or multi-version installs as they call it) http://wiki.wxpython.org/index.cgi/MultiVersionInstalls. This may be relevent to other wxWindows problems so I hope it gets found on searches.
