Subject: [ruby-talk:4756] Re: Which distribution (was Windows registry)


I have downloaded two distributions and neither of them have an ext
directory.

My files are:

    rbcw145.zip
    ruby-1.6.0-20000829-i386-cygwin.tar.gz

To add to the confusion those two distributions contain totally different
directory structures.

Which distribution should I be using and why are there so many spread around
different pages?  As a new user I'm finding the installation procedure
somewhat confusing.  There appear to be all sorts of required DLL's that are
separate from the main distribution file.

Is there a single download available that includes all necessary files
packaged into an install program?

Thanks for your help,

    Glen
