I use plain Vim with ruby support on Lion (installed by gist). I am using ruby with rbenv so my path looks like /users/me/.rbenv/shims:…..
From within vim the path is
:!echo $PATH > usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/X11/bin:/Users/fb/.rbenv/shims:....
Even I can create and modify an environment variable:
:let $PATH = "/bar:/foo" :!echo $PATH > /usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/X11/bin:/foo:/bar
paths remains starting with /usr/bin.
So how can I access my ruby 1.9.3 in ~/.rbenv/shims instead the system ruby in /usr/bin ?
