jpeg +universal fails to build

[Gianluca Toso]

Hi,
I have this problem[*], it seems almost the same reported here:
http://trac.macosforge.org/projects/macports/ticket/12320

There is a solution?
libjpeg.dylib is compiled only for ppc.
The libtool and gcc -dynamiclib lines that compile libjpeg.dylib don't 
contain -arch options.
But I don't find where in Makefile or other file is the problem.

My system:
OSX 10.4.10 PPC
XCode 2.4.1
last MacPorts

The other errors may be the usually ppc problem (ld and syslibroot).
