Yes, gnucash does set DYLD_LIBRARY_PATH. The justification for their  
adding it was to allow gnucash to pass make check on a mac. (one  
symptom being that configure can find MSGFMT, but make can't).

Jeff,
The patch I use for this is:
   perl -pi.bak -e 's,DYLD_LIBRARY_PATH,DYLD_FALLBACK_LIBRARY_PATH,g'  
aclocal.m4
   perl -pi.bak -e 's,DYLD_LIBRARY_PATH,DYLD_FALLBACK_LIBRARY_PATH,g'  
configure
   perl -pi.bak -e 's,DYLD_LIBRARY_PATH,DYLD_FALLBACK_LIBRARY_PATH,g'  
src/bin/gnucash.in
   perl -pi.bak -e 's,DYLD_LIBRARY_PATH,DYLD_FALLBACK_LIBRARY_PATH,g'  
src/bin/overrides/gnucash-env.in
   perl -pi.bak -e 's,DYLD_LIBRARY_PATH,DYLD_FALLBACK_LIBRARY_PATH,g'  
src/gnc-test-env
