You should not hard-code the full path of a header file like

#include </usr/include/ruby-1.9.1/ruby/ruby.h>

proper is

#include <ruby.h>

and told your gcc to search the header file via CFLAGS and libariy via LD_FLAGS, simply command without makefile could be:

gcc -o demo.exe -I/path/to/ruby/headers rubydemo.c -L/path/to/ruby/lib -lruby-libary-name
