Installing haml/sass through rubygems

Question

meder@dunross:~$ sudo gem install haml
Successfully installed haml-3.0.12
1 gem installed
Installing ri documentation for haml-3.0.12...

meder@dunross:~$ haml
bash: haml: command not found

It seems like it installs haml then comes across something and doesn't install the full way. I have rubygems 1.3.6-2 and ruby 1.8.x. Debian Lenny OS.

Has anyone had this issue before or know what it could be?

Extra information:

meder@dunross:~$ gem list

*** LOCAL GEMS ***

haml (3.0.12, 3.0.9)
maruku (0.6.0)
syntax (1.0.0)
yard (0.5.8)
meder@dunross:~$ gem list haml

*** LOCAL GEMS ***

haml (3.0.12, 3.0.9)

Update #1: I realized I installed 2 versions of haml, so I got rid of them both:

meder@dunross:~$ sudo gem uninstall haml

Select gem to uninstall:
 1. haml-3.0.9
 2. haml-3.0.12
 3. All versions

meder@dunross:~$ echo $PATH

Might be a $PATH thing in that it isnt picking up the rubygems directories

Answer 1

Ok. I appended my $PATH with :/var/lib/gems/1.8/bin and that seemed to do the trick.

Answer 2

The "Could not find README" notices aren't errors. Haml doesn't use RDoc, but Rubygems doesn't have a good way of saying that, so it still looks for README.rdoc.
