Sounds like you should check $PATH before and after the change to see
what it's actually doing. 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.
echo "PATH: $PATH"
before setting and after to see what's going on. then it's just a matter
of figuring out which ruby comes first.
