Intel mac instant client is for Mac OS X 10.5.
It doesn't work on Mac OS X 10.4 or before.

You have three workarounds.
1. Compile ruby as ppc binary and use it with ppc instant client.
2. Use JRuby and JDBC
3. Use a third-party ODBC driver and ruby-odbc.

You may need to set the environment variable RC_ARCHS or ARCHFLAGS as follows:

  export RC_ARCHS

  ARCHFLAGS='-arch #{my_arch}'

If it does not fix the problem, delete all '-arch #{missing_arch}'
