I install ruby via a binary rpm, however I have a requirement to provide  
swig with the ruby header file. Where in the directory structure should  
I put it? “/usr/lib/ruby/1.8/include”? “/usr/lib/ruby”?

Regards,  
Jim

ruby.h should always be here:

ruby -rrbconfig -e ‘puts Config::CONFIG[“archdir”]’

After the light went on I installed the ruby-devel-1.8.4-1.c4.i386.rpm  
for  
CentOS4, which provided everything I needed and put it all in the right  
places.
