Of course, a little reading makes you stumble into stuff like this:

http://rvm.beginrescueend.com/workflow/prompt/

So, all you need is LOVE. And this on your .profile:

PS1=”[\h:\$(~/.rvm/bin/rvm-prompt)]\W \u\$ “

You probably don’t have a RUBY_VERSION variable on 1.8.7 because you’re using the system ruby.

Try installing rvm’s 1.8.7 and setting it as default

rvm install 1.87
rvm 1.8.7 –default

Now, what I did was extract the ruby version and the gemset from $GEM_HOME, something like this:

RUBY_WITH_GEMSET=$GEM_HOME
RUBY_WITH_GEMSET=${RUBY_WITH_GEMSET%%/[ruby]*}
export RUBY_WITH_GEMSET=${GEM_HOME:(${#RUBY_WITH_GEMSET} + 1)}
export PS1=”[\h:${RUBY_WITH_GEMSET}]\W \u\$”

Now I can see the ruby version and the gemset on the prompt, if you don’t care about the gemset, you can just use RUBY_VERSION on PS1.
