I know in the aolserver 2.3.3/Linux days, the server was very sensitive to versions of glibc. It'd work fine on one distro but then fall over horribly on another. Since the 3.X source is out, it should be easier to fix things like libc dependencies (or work around problems in the system libraries. Fer instance when I tried porting AOLserver 2.X to free BSD 2.something, I ran into a some threading problems in the kernel and in the C libs)
