Has anyone had any luck compiling the ruby-odbc library on Mac OS X
Leopard?  I've been following the instructions found here (http://
www.napcsweb.com/blog/2007/03/08/15/), which worked on Mac OS X
Tiger.  Everything works in Leopard, save for ruby-odbc.   When I try
to make the library, I get the following error:

cc -arch ppc -arch i386 -pipe -bundle -o odbc.bundle odbc.o -L"." -L"/
System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib" -L. -
arch ppc -arch i386    -lruby -liodbc  -lpthread -ldl -lm
Undefined symbols for architecture i386:
  "_SQLConfigDataSource", referenced from:
      _conf_dsn in odbc.o
ld: symbol(s) not found for architecture i386

lipo: can't open input file: /var/tmp//cc7qgHlP.out (No such file or
directory)
make: *** [odbc.bundle] Error 1


Here's the commands I am typing into the Terminal:

> ARCHFLAGS="-arch i386" ruby extconf.rb
> make

Anyone had any luck?

Thanks for the help.
