Dave said it below: DYLD_LIBRARY_PATH *overrides* the search order. So you're searching /usr/local/lib, then /sw/lib, then /usr/lib. DYLD_FALLBACK_LIBRARY_PATH doesn't override the search order, but appends to it. (hence the name) However, since as Dave said, binaries encode the full path to any libraries, typically you don't even need to specify DYLD_FALLBACK_LIBRARY_PATH. Building using Fink with libraries in /usr/local/lib may well set you up for problems down the road, BTW, if you get any cross-linkage. We recommend moving /usr/local out of the way while you do Fink builds. - -- Alexander Hansen Fink User Liaison > On Jun 28, 2010, at 16:16 , David R.
