Subject: compiling opengl

hi

i am trying to compile opengl for ruby. I found two different distros on
the net, one of them looked like had been prepared for OSX where i work
mostly. I follow carefully the instructions on both with no luck, I
paste below the errors, if anyone could help it would be great.
many thanks


the first time I tried with opengl-0.32f, this one looked like prepared
for OSX

Ordenador-de-r2d2:/Volumes/data/software/ruby/opengl-0.32f r2d2$ ruby
extconf.rb
extconf.rb:36: undefined method `+' for nil (NameError)

----------------

This is the second one with  opengl-0.1.32f

Ordenador-de-r2d2:/Volumes/data/software/ruby/opengl-0.1.32f r2d2$ ruby
