Subject: More installer questions

Hi:

I have a few questions about the installer. 

I noticed that when compiling, the <prefix> path is included
in the compile. Why would this path be included since it is
not even known to exist?
For example, if prefix is set during ./configure, it shows up during
make as:

gcc -g -O2 -I. -I. -I<prefix>/include -c array.c


My next question is what does it really mean when the libs in
ext/Setup are uncommented. I know that the docs say it means 
to statically link libs, but I also perceive that those libs are not linked
into the ruby executable, or I would not get the error:

 -> ./irb 
irb(main):001:0> require 'tk'
LoadError: No such file to load -- tcltklib
        from /home/jfreeze/ruby/lib/ruby/1.6/tk.rb:7:in `require'
        from /home/jfreeze/ruby/lib/ruby/1.6/tk.rb:7
        from (irb):1:in `require'
        from (irb):1

Even though I was able to successfully compile ruby with a limited
path, I could not run ruby with that same path.

Incidently, the above error goes away if I add /usr/local/bin to the path.
But I don't understand this since the tcltklib is not in /usr/local/lib.

And, my last question. I compiled a local static version of ruby
and set my path to /bin:/usr/bin:<prefix>/bin.
Running ruby works fine, but running irb without the full path
to irb produces the error:

-> irb
/home/jfreeze/ruby/lib/ruby/1.6/irb/completion.rb:10:in `require': No such file to load -- readline (LoadError)
        from /home/jfreeze/ruby/lib/ruby/1.6/irb/completion.rb:10
        from /home/jfreeze/ruby/lib/ruby/1.6/irb/init.rb:197:in `require'
        from /home/jfreeze/ruby/lib/ruby/1.6/irb/init.rb:197:in `load_modules'
        from /home/jfreeze/ruby/lib/ruby/1.6/irb/init.rb:195:in `each'
        from /home/jfreeze/ruby/lib/ruby/1.6/irb/init.rb:195:in `load_modules'
        from /home/jfreeze/ruby/lib/ruby/1.6/irb.rb:52:in `start'
        from /home/jfreeze/ruby/bin/irb:13

But, specifying the full path seems to work:

 ./irb 
irb(main):001:0> 

Can someone tell me why is the full path to irb needed in this case.


Thanks much.
