Welcome to the better side ;-) or that should maybe be  :P

Locomotive is great, but it all depends on what your needs are.

I too have three installs and it all works perfectly, and you should  
absolutely NOT remove the Tiger installed ruby as that may break your  
system. (?)

I can't see a single valid reason to why you should un-install the  
'ports' version, unless of course you'd want to compile your own  
version. So don't ;-)

Not 100% sure I fully understand you there, but AFAIK Locomotive  
opens up a new Terminal window with all the correct PATHs set if  
opened from within Locomotive.

$ echo $PATH
/Users/mats/Applications/Locomotive2/Bundles/ 
rails112rmagick_ppc.locobundle/framework/bin:/Users/mats/Applications/ 
Locomotive2/Bundles/rails112rmagick_ppc.locobundle/framework/sbin:/ 
usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/Users/mats/bin:

$ which ruby
/Users/mats/Applications/Locomotive2/Bundles/ 
rails112rmagick_ppc.locobundle/framework/bin/ruby

in normal Terminal window:
$ which ruby
/usr/local/bin/ruby

So based on what you're working with, you'll get the correct ruby.

As for MANPATH, well, neither of those produces any output on my  
system, and AFAIK the Locomotive bundles does not seem to contain man  
pages.

It can only 'get in the way' IF you don't have the correct PATH set  
in .bash_login or .bash_profile, so make sure your $PATH is something  
like:

export PATH="/usr/local/bin:/usr/local/sbin:/usr/local/mysql/bin:$PATH"

Make sure your path to ruby is in the front of the PATH variable,  
before Apple's Ruby install.

Hope the above is at least some help on the way.

Kind regards,

Mats
