mac os x 10.6 installation error

Sorry for the newbie question. I'm really trying to install PyGUI
which requires PyObjC. The target is a macbook pro with the standard
Apple python 2.6. I ran easy_install pyobjc; after several paragraphs
of this-n-that it failed for lack of GCC. Oops, I'd never installed
XCode on this machine. I got out the snow leopard dvd and installed
Xcode and reran the easy_install.

Now it goes almost immediately to compiling a _ScreenSaver_ module
which after a number of warnings, fails as follows:

  lipo: can't open input file:
/var/folders/Et/EtxW7vM0HTaS6E9e2To88E+++TI/-Tmp-//ccHZxEai.out (No
such file or directory)
  error: Setup script exited with error: command 'gcc-4.2' failed with
exit status 1

It may be significant that if you Google 'lipo: can't open input file'
you get many hits related to installing a variety of packages such as
pygame, mysql, etc hence this may be a generic easy_install issue with
Mac 10.6.

I'll put the whole voluminous record below, feel free to snip it in any reply.

Thanks for any insight,

Dave Cortesi
