ideally in a way that still permits building 32 bit binaries on 64 bit
systems. However, "it" does seem to "work out of the box" for most people,
which is why the bug remains. I suspect it works because 1) ld has
/usr/local/lib64 in its default search path, so OSG libraries are picked
up, 2) people don't realize that they are polluting /usr/local/lib with 32
bit simgear libraries, 3) the flightgear compilation command includes
-L/usr/local/lib even on 64 bit libraries, so everything seems hunky-dory,
or 4) people (like myself) never install simgear and flightgear in the
system directories.
