Subject: "gem install mysql" failing horribly on OS X leaopard

Hi -- I'm having trouble getting the mysql gem to install on an OS X
Leopard machine.
Typical output I get from the console is this:

<CONSOLE>
esft 523 $ sudo env ARCHFLAGS="-arch i386" gem install mysql --
--with-mysql-include=/usr/local/mysql/include
--with-mysql-lib=/usr/local/mysql/lib

Building native extensions.  This could take a while...

Could not create Makefile due to some reason, probably lack of
necessary libraries and/or headers.  Check the mkmf.log file for more
details.  You may need configuration options.

Provided configuration options:
  --with-opt-dir
  --without-opt-dir
  --with-opt-include
  --without-opt-include=${opt-dir}/include
  --with-opt-lib
  --without-opt-lib=${opt-dir}/lib
  --with-make-prog
  --without-make-prog
  --srcdir=.
  --curdir
  --ruby=/usr/local/bin/ruby
  --with-mysql-config
  --without-mysql-config
  --with-mysql-dir
  --without-mysql-dir
  --with-mysql-include=${mysql-dir}/include
  --with-mysql-lib=${mysql-dir}/lib
  --with-mysqlclientlib
  --without-mysqlclientlib
  --with-mlib
  --without-mlib
  --with-mysqlclientlib
  --without-mysqlclientlib
  --with-zlib
  --without-zlib
  --with-mysqlclientlib
  --without-mysqlclientlib
  --with-socketlib
  --without-socketlib
  --with-mysqlclientlib
  --without-mysqlclientlib
  --with-nsllib
  --without-nsllib
  --with-mysqlclientlib
  --without-mysqlclientlib


Gem files will remain installed in
/usr/local/lib/ruby/gems/1.8/gems/mysql-2.7 for inspection.
Results logged to
/usr/local/lib/ruby/gems/1.8/gems/mysql-2.7/gem_make.out

</CONSOLE>

And when I look in the mkmf.log file, at the end of a very long series
of entries, I see this:

<LOG>
"gcc -o conftest -I. -I/usr/local/lib/ruby/1.8/universal-darwin8.0 -I.

</LOG>

Can anyone offer me any advice on getting this to work?
Cheers,
   Doug.
