Yes, it is wrong - as I said, with a fresh install of FC6 on x86_64,
/usr/lib64 and /lib64 aren't listed in /etc/ld.so.conf or any file it
includes.  Instead, ldconfig implicitly searches them (like it
traditionally implicitly searches /usr/lib and /lib).

However, libtool doesn't know about these extra implicit paths (which I'm
not totally suprised by as it's probably a recent development - too recent
to have been documented in the ldconfig man page at least!)

Indeed, but what I find suprising is that you *did* get /lib64 and
/usr/lib64.  This presumably means that they are listed in your
/etd/ld.so.conf or some included file on your machine (perhaps this is a
difference between a fresh install and an upgraded one).  And it's also
strange that you get the rpath given that libtool knows that /usr/lib64
is a standard library path on your machine.

But ignoring such mysteries, libtool gets this wrong on a fresh install
of x86_64 FC6 and that really needs fixing.  I'll report it to the
libtool developers.
