Want use compass & sass and some "gems" for the compass.

I know nothing about the ruby and his ecosystem, and honestly - i need only the running compass watch - nothing more.

Because don't want touch the system-wide installed ruby, want use the macport's one.

I'm already using the macports for many packages, of course have the all OS X developer packages installed (Xcode + command line tools), therefore this question isn't a duplicate to this one.

Could please someone write how to use the macport's compass?

Already did:

$ sudo port install ruby
$ port select --list ruby 
Available versions for ruby:
none (active)
ruby18

so activated the macports one

$ sudo port select --set ruby ruby18

ok, now the type ruby return /opt/local/bin/ruby. So, installed the rb-rubygems package

sudo port install rb-rubygems

but the type gem still returns /usr/bin/gem :(

also installed 

 $sudo port install rb-compass

but the compass command is still /usr/bin/compass - simply terrible.

So, please - could someone give an advice how to activate and use the whole macports ruby-suite? Some step-by-step guide would be nice. I simply need:

  • compass (+ some gems for the compass)
  • sass (needs it the compass)
  • ruby
  • gem
  • and whatever else what is needed for the compass.

Ps: i haven't problem with any other macport's packages - only the "ruby+macport logic" is somewhat unclear for me.

MacPorts avoids installing stuff in places that could also be used by the same software using different ruby versions. For this reason, rb-compass does not install to /opt/local/bin/compass where you would expect it. It does, however, install the compass executable in a couple of places you could use directly, add to your path, or symlink from /opt/local/bin/compass:

$ port contents rb-compass | grep -E 'compass(-1.8)?$'
  /opt/local/bin/compass-1.8
  /opt/local/lib/ruby/gems/1.8/bin/compass
  /opt/local/lib/ruby/gems/1.8/gems/compass-0.12.2/bin/compass
  /opt/local/libexec/ruby1.8/compass
