Tried to get this working with Skype 6 on OS X 10.8.5, but with no success. Have you tried that, hopefully, with any good results?

F-Script not supported on OSX 10.6 and above -- saw note on http://sabi.net/nriley/software/

I there the way to do it without GDB? I do't want to install it on Mavericks.

It's working just needs updated with lldb and use last version Kentzo/F-Script#12 see my fork https://gist.github.com/onemanstartup/a240051b05d4858593d7

Please excuse my ignorance, but I feel a bit lost here. I've downloaded and installed F-script (moved the files to Applications- and appropriate Library-folder?), installed Xcode and downloaded onemanstartup's version of SkypeMenuUpdater.rb. I then ran the ruby script in a Terminal window by writing "ruby SkypeMenuUpdater.rb". Nothing appeared in the terminal and I don't get any updates on the icon. I'm running Yosemite and the latest version of Skype. Is there anything I'm doing wrong?
