Problem installing on Mac OSX

I tried the instruction tutorial on

and in the middle of trying to install fixrbconfig I got an error:

usr/lib/ruby/1.8/powerpc-darwin8.0/ruby.h does not exist. This probably
means you haven't yet installed Xcode from the Tiger DVD. You won't be
able to compile Ruby extensions without it. Please install it then rerun
this program.

I had installed Xcode.

Any clue?

Also, I'm bothered by this error and the fact that configuration needs
to be fixed. Why do I need to "fix" something after installing it, why
do I have to use terminal to do it, and why do I have an obscure error
like this one?

The main problem I see with languages and scripts like Ruby on Rails,
PHP, etc. is that they will never be distributable to everyone who
really needs them because the task of installing the underlying
application is so daunting. Any discussion in the open source community
about solving that problem?

You can reset the password with a Mac OS X installation disk (see
