I recall we re-export DYLD_FALLBACK_LIBRARY_PATH in cases where it's needed - e.g. rJava uses in configure: DYLD_FALLBACK_LIBRARY_PATH=`"${RBIN}" --slave --vanilla -e 'cat(Sys.getenv("DYLD_FALLBACK_LIBRARY_PATH"))'` export DYLD_FALLBACK_LIBRARY_PATH > > I was actually using install_name_tool -change in our build of the stats.so > to patch up the refs to lapack and blas.
