Not so easy to get a reall 11.2 :? .
I used the netinstaller iso (for 11.2), but all repos where set to 11.1, I had to manually change them to 11.2 and the update a bunch of files (about 1 GB).
Seems to be my error, I accidently fetched the 11.1 netinstall-iso, but used the 11.2 repos for install (changed it while install-procedure).
Nevertheless I finally managed to do so, installed wxWidgets 2.8.10 from opensuse and C::B from the repo you pointed me.
Everything is fine.
I should say, that I use a 32-bit systems (except for my real system), but that should not make adifference (at least not in this case).
Which version of C::B do you have ?
It's 5919 here.
EDIT2:
Just saw you used 5911, maybe you should update your C::B.
Nevertheless I try a 64-bit suse also.
