Please bear with me, as my UNIX is extremely basic, and this
is the first time I have installed anything. I would
like to upgrade to 1.8 when I am competent enough.

A couple of questions.
--------
Here is my output from running test.rb from the
extmath-2.3 package.

When I look at the InstalledFiles in extmath-2.3, I get

[jacques-computer:~/ruby/extmath-2.3] sylvanjacques% cat
InstalledFiles
/usr/lib/ruby/site_ruby/1.6//extmath.rb

What does the double // mean in the path name?

Here is the config.save file;

-------
the so-dir is
/usr/lib/ruby/site_ruby/1.6/powerpc-darwin6.0
It's an empty directory.
The INSTALL doc from extmath-2.3 says that so-dir
is the directory for ruby extentions. Does this mean
that extmath.rb and rubyunit.rb (and runit) should be in the
powerpc-darwin6.0 dir? Or are they in the right place.
If so, why the error messages when running test.rb
from extmath-2.3?
