well you have libgcc for gcc3.4.3 but NOT for the gcc-3.3.5 which you have installed...
so maybe choose one and get teh rest of the pkg for it

about :
System:
Debian Sarge with a aMule-cvs-20050312 running (not very stable).
well cvs is atm also a little unstable, since we start now working on some new stuff, and this makes cvs, not as stable as amule-2.0 is....so if you want stable amule use 2.0
another fact is that debian is still using wxGTK-2.5.3, which is definetly not the best.
so even if you compile amule-cvs/2.0 yourself this wont improve that much. webserver will work better, since this is kinda brocken in vollstreckers-deb-pkg. but if you get amule-crashes, you should also compile wxGTK-2.6 yourself and link your self-compiled-cvs against it.
