whenever I install something via gem which presents a menu of options to me (versions, and 'ruby' vs 'mswin32' , I make my selection and it gives me this: > 1 Building native extensions. This could take a while... extconf.rb:4:in `require': no such file to load -- mkmf (LoadError) from extconf.rb:4 ERROR: While executing gem ... (RuntimeError) ERROR: Failed to build gem native extension. Gem files will remain installed in /var/lib/gems/1.8/gems/fxruby-1.6.11 for inspection. Results logged to /var/lib/gems/1.8/gems/fxruby-1.6.11/ext/fox16/gem_make.out (gem_make.out is empty, by the way. er, well, 1 byte.) not sure what's going on... gem installs fine when there's no option menu, but maybe that's a misleading correlation, no clue... new to ruby and programming in general here. erm, another thing, somewhat ruby-related... is that scite won't let me use 'irb' like it's supposed to, and I have no idea why. it says this: >irb sh: irb: not found >Exit code: 127 thanks! and btw- WOW, what an amazing community. keep it up. :)
