ruby

I was checking. echo $PATH reports correctly. If I source the .bash_profile more than once, however, I get duplicates.

Whatever you want to run, say your version of ruby in /some/dir/ruby, needs to appear earlier in the path than the system version, say /usr/bin/ruby... period. It's not rocket science. However, it's not totally straightforward, either. Some updated  command locations require that the shell be rehashed after changing the path cuz the shell may cache the location - hash -r, or equivalent. That said, it's usually pilot error messing with path.
