1/ that's really strange place to look for the header files
   (/usr/include/ tree is pretty standard for system-wide headers)

2/ perhaps you are after /usr/include/ruby.h from ruby-devel package

3/ if you look at that README carefully, you may notice the pcs
   maintainers are mentioning Fedora distribution in particular,
   so things may be a bit more complicated elsewhere
