Sorry for the stupid question. I am trying to build  
rubyOSA 0.2.0 on my Mac Powerbook, OS X.4.8.  
When I run "ruby extconf.rb", following the instructions,  
I get the answer "can't find header files for ruby".  
When you stop laughing, please, tell me: what should I do?

Thanks a lot,  
Piero

Hi Piero,

Did you install the developer tool package? IIRC you can install it  
from the Mac OS X installation DVD.

(You can check this by running 'gcc' on the terminal, if you see  
'command not found' you don't have the developer tool package.)

HTH,  
Laurent

It is looking for the ruby.h file.

In Ubuntu/Debian I install the ruby-dev package to get those header  
files. I assume there is a similar package for Mac.
