Some people have tried.

Here is what I add to the README file in the next ruby-oci8 release.

=== Intel Mac

Oracle intant client is still, when I write this, pcc.

1. check whether the ruby is ppc bianry.

      file `which ruby`

   If it is universal bianry, use ditto to extract ppc binary.

      http://blog.sven-tissot.de/daylist_html?year=2006&month=4&day=12

   If it is i386 binary, compie it as ppc.

2. fix compilation flags.

      ruby -r rbconfig -e "p Config::CONFIG['CFLAGS']"
      ruby -r rbconfig -e "p Config::CONFIG['DLDLAGS']"

   If they have '-arch i386', delete it from:
      /usr/lib/ruby/1.8/powerpc-darwin8.0/rbconfig.rb
   or
      /usr/lib/ruby/1.8/universal-darwin8.0/rbconfig.rb

   If they haven't '-arch ppc', add it.

3. config, make and install

     ruby setup.rb config -- --with-instant-client=/opt/oracle/instantclient10_1
     make
     make install

4. rollback the changes in 2.
