expansion pak ruby installation comments

[Michael Han]

Hi why and list,

great work, i cannot wait to see the tiger explore something ruby 
debugger related.

now some comments on installing ruby, as described in your expansion 
pak:

OSX:
as far as I know, if you compile ruby from source it will install to 
/usr/local/ by default so you will need to sudo or become root to write 
there for the make install.
Tiger (10.4) should have 1.8.2 already preinstalled?

FreeBSD:
you can also use sysinstall (the pretty curses thing) to get the binary 
package for ruby or use pkg_add -r ruby18 .
And you will not be able to use sudo on FreeBSD if you haven't 
installed it from ports/packages.

happy installing,

Michael
