Comment(by mcalhoun@…):

 I just ran into this problem.[[BR]]
 I tried to upgrade jpeg to get a universal build (so while jpeg was
 building, a non-universal /opt/local/lib/libjpeg.dylib existed).[[BR]]
 At one point in the build process, there is the command:
 {{{
 /usr/bin/gcc-4.0 -L/opt/local/lib -arch ppc -arch i386 -arch ppc64 -arch
 x86_64 -mmacosx-version-min=10.5 -o .libs/cjpeg cjpeg.o rdppm.o rdgif.o
 rdtarga.o rdrle.o rdbmp.o rdswitch.o cdjpeg.o -L.libs -ljpeg
 }}}
 Since -L/opt/local/lib is before -L.libs, the linker finds
 /opt/local/lib/libjpeg.dylib (not universal) instead of
 .libs/libjpeg.dylib (universal).

 Attached is a proposed fix.

 It is a long shot, but this may be related to #17910.[[BR]]
 If
 /System/Library/Frameworks/ApplicationServices.framework/Versions/A/Frameworks/ImageIO.framework/Versions/A/Resources/libJPEG.dylib[[BR]]
 was in the library search path, then the above command might have found it
 as well.
