should be relocatable, at least that is the usual expectation (and is why
the `sage-location` script is/was always run, though with the reorganized
structure I'm still getting used to a few changes that may have happened
recently.)

> Well, as mentioned on the original ticket, Darwin's `install_name`
mechanism also supports flavours of ''relative'' paths, but François told
me that those features are only available on MacOS X 10.5 (or probably
10.6) and later, so we'll presumably have to treat 10.4 specially (at
least if we want to avoid useless rewrites or effectively no-ops).
`dyld`'s manpage on your 10.4 system should tell what's supported, not
necessarily `ld`'s. (It would also be interesting whether it supports
`DYLD_FALLBACK_LIBRARY_PATH`.)

@rpath is OS X 10.5+ but @loader_path and @execute_path are in 10.4. As it
happens we wouldn't want @rpath I think. @loader_path is apparently
filling the same role as "Origin" under linux. And @loader_path is what is
in polybori. I just don't know if it is correct in there.
