One of the biggest shell script portability issues I've run into - going between Linux and OS X (BSD variant) - is not with bash itself, but with tools like sed being slightly different.  The solution on OSX is to use the gnu tools (i.e. gsed) from homebrew - but it's confusing until you know that's what's happening.
