You can try ubuntu 14.04 (32bit !!!), it does not have pre-installed rtmpdump.
Usually the whole process is simple:
compile and install rtmpdump-ksv
install nodejs
clone the chaturbate code
install node libraries
run
As for your current VM, have you tried to find existing rmtpdump libs?
# sudo find / -name "librtmp.so.*" -exec ls -al {} \;
If you find several files like librtmp.so.0 or librtmp.so.1 you should try to replace them by the same file from your rtmpdump-ksv folder (pay attention to filesize)
