Hi!

I'd like to propose a small patch for make_ctags script. It checks if ctags 
utility is intalled or not. If not it reports an error and advises to install 
ctags.

This will make life of a person that uses ctags first time in his life a bit 
easier.

I use command -v to detect if ctags command exists. It is POSIX standard and I 
hope it exist in all shells.
