Are you setting DYLD_LIBRARY_PATH=/sw/lib or something similar? Don't do 

The problem you are seeing is due to a combination of several 
unfortunate circumstances, not the least of which is the brainfart of 
some Apple engineers that led them to the bright idea to put a file 
named libJPEG.dylib into their System ImageIO.framework. The 
not-very-principled dynamic loader dyld easily confuses this with 
/sw/lib/libjpeg.dylib (there is *no* /sw/lib/libJPEG.dylib!)

In the case of scribus, I haven't seen this confusion unless 
DYLD_LIBRARY_PATH was set. You don't need this environment variable; use 
LDFLAGS, PKG_CONFIG_PATH, --with-qt-libraries=/sw, 
--with-extra-libs=/sw, etc.

Another elegant solution of the problem is to do your building in a 
case-sensitive file system. You don't need to repartition your disk for 
this, just create a 5-10GB Build.dmg and put a HFS+-case-sensitive (not 
UFS!) filesystem on it. When you build your scribus there, you won't see 
this problem.
