We had a discussion on glasgow-haskell-users recently about whether

Hmm, I missed that one completely. It's probably too late for me to
jump in but I just don't see how the approach you outlined in
http://www.haskell.org/pipermail/glasgow-haskell-users/2007-June/012740.html
deals with systems which don't *have* an rpath and with users who
manually set LD_LIBRARY_PATH. To be entirely honest, I suspect that
what you are trying to achieve can't be done portably and reliably.
I don't expect it to be portable. So on MacOS X, is it the case that
the only way to build a binary that links to a particular shared library
outside the system location is to use LD_LIBRARY_PATH?
IIUC yes, except that it's called DYLD_LIBRARY_PATH. From man dyld:
For each library that a program uses, the dynamic linker looks
for it in each directory in DYLD_LIBRARY_PATH in turn. If it
still can't find the library, it then searches DYLD_FALL-
BACK_FRAMEWORK_PATH and DYLD_FALLBACK_LIBRARY_PATH in turn.
But I think on MacOS, the library paths are usually hardcoded in the
executable.
How does libtool work on this OS?
Not sure, I'll have to look that up.
