I followed the instructions for installing visual ruby - install ruby
193 and glade, then in a ruby window typed ‘gem install visualruby’ and
got the following output which shows the gem install output, and what
happened when I typed vr.
I’m a complete noob in this area so it’s probably something very obvious
to the ‘knowledgeable ones’ but I’d appreciate some advice.
A preview of the output after I pasted it here was unreadable, so I’ve
put it in the file I’ve attached.
Visualruby install failed. info follows:
ERROR: Error installing visualruby:
ERROR: Failed to build gem native extension.

Any advice ?
Nort sure I did this correctly.
