Hi!

Thanks for updating this project and bringing it back. :)

When I was going through the installation instructions I ran in to a problem running omake. The output looked like this:

> omake install

I was using the version of Ruby specified in the rbenv file in the project (2.3.4).

The fix was pretty simple. I just renamed the stubs/2.3 file to be stubs/2.3.0, but this seemed like a bug.

[~/diamondback-ruby/stubs]> mv 2.3 2.3.0
[~/diamondback-ruby/stubs]> cd ..
[~/diamondback-ruby]> omake install
*** omake: reading OMakefiles
*** omake: finished reading OMakefiles (0.23 sec)

Is the idea that druby only cares about the Ruby version up to the minor version? Does there need to be a change to the ocaml makefile to detect the version more loosely?

Thanks again!

Thanks for report. What is your operating system?

Oh sorry: Mac OS 10.12.6
