this is a big commit, I updated my ubuntu server to 13.10 from 12.04 and found that byobu is not working properly anymore, I find the new versions of byobu can be in conflict with my local modifications, so I decdied to put the byobu source(from git) inside dotfiles/.byobu/SRC_GIT. With this setup, BYOYU_PREFIX is set to /home/xcui/.byobu inside my .bashrc_custom, so byobu will look for share/byobu and lib/byobu inside my .byobu directory. I then created symbolic links of lib/byobu and share/byobu to the corresponding directories inside SRC_GIT. Mofidied some sources files inside SRC_GIT to make it work like before. For details of modification, you can grep xcui in the directory root or check out my evernode notes or use git diff inside SRC_GIT
