Hello Patrik.

Indeed the message didn't arrive the list, which requires you to join.

Soon I'm going to open a Google Groups for this with the goal of
better manage the subscription and also simplify the process of people
reporting issues like yours.

Please read my inline answers to your questions. I'm CC'ing to
RubyInstaller-devel list so others can learn from those.

Unless you build the MSI installers using the updated-installers
branch, the built MSI packages are set to failure.

(see Installers topic)

I suggest you use the 7z packages instead of the MSI.

That definitely is a old version of Rake and Ruby that generated that.
Rake prior to 0.8.4 and/or Ruby 1.8.6-p287 has failures with
Kernel::system() and that translate into Rake "sh".

Solution: use one of the 7zip packages when building :-)

If you used master branch, those files are no more. Check the
updated-installers branch. The MSI packages really need some love :-P

Yes. the WXS files need to be updated to include the pure-ruby
readline. All the work on that has been done on updated-installers
branch, not master.

Solution: Unless you really need to generate and run the installers,
stick to the 7zip packages.

On top of these packages, install the rb-readline 0.1.2:

Thank you, there are still a lot of glitches :-P

I'll suggest stay away of devkit package. DevKit is dead. I've
actually killed that package in updated-installer branch.

Yes, we are going the devkit gem route, but is not ready for prime-time yet. :-P

Thank you for your feedback!
