Thanks for the help. Did re-install: doesn't solve the problem.
I also lookued up, if the library is actually installed:
$ locate libwx_gtk2u_aui
/usr/lib/libwx_gtk2u_aui-2.8.so.0.1.1
/usr/lib/libwx_gtk2u_aui-2.8.so
/usr/lib/libwx_gtk2u_aui-2.8.so.0
The installed wx-lib is 2.8.4.0-0: Does that mean, I have to try to install a 2.8.5 lib of wx? Doesn't show up with an update of wx on my system. If I am the only one, there must be something broken on my system.
I may actually wait for the next nightly build and see, if the error goes away ... and fix it then, if it remains.
See you,
Flex
