I guess I don't understand how I am supposed to set up my build
environment....  As far as I can tell, config.h is generated while
building Ruby from source.  The only config.h on my system is:

/usr/lib/ruby/1.8/i386-linux/config.h

Which does not have WORDS_BIGENDIAN listed in it.  I did find
WORDS_BIGENDIAN in /usr/lib/ruby/1.8/i386-linux/defines.h but it just
says to look at __BIG_ENDIAN__.

Can you point me to a small project that I can model my build after, or
an example exconf.rb?

Thanks for the help!
