Linking to the tk directory

[John Slimick]

I am new to ruby, so I need some help.
I want to use tk widgets when I teach ruby.
I have downloaded and installed the ruby-1.8.6-p110
distribution. When I tried to do the
"Hello World" window in ruby/tk, irb
could not find tk. I can find the tk directory
which is at:

/home/fred/Desktop/ruby/ruby-1.8.6-p110/ext/tk

Is there a shell variable I need to set that
contains where tk is? I couldn't find much
help on google.

Thanks in advance

That directory only contains the Ruby library that acts as a bridge
between Ruby and Tcl/Tk.

Is there a shell variable I need to set that

Probably not a shell variable problem (although there is a chance it
is a PATH problem). It is more likely that Tcl/Tk is not installed on
your system. Perhaps this URL will help.
