why is your libelf.h including linux/sys.h ?  mine isnt:
$ grep '#include' /usr/include/libelf.h
#include <sys/types.h>
#include <elf.h>

crap, wrong log.  sorry.

off64_t only shows up when building with -D_LARGEFILE64_SOURCE ... wtf thought
that was a good idea

add this to the top of your libelf.h:
#if !defined(_LARGEFILE64_SOURCE) && !defined(__off64_t_defined)
# define _LARGEFILE64_SOURCE
#endif

and make sure things work

nope, sorry.  still getting the same error.

do `sed -i 's:off64_t:__off64_t:'` on libelf.h ... that lets me build prelink

I wonder how this was ever supposed to work on redhat.. I'd vote for doing the
sed in a -r1 ebuild.

*** Bug 204208 has been marked as a duplicate of this bug. ***

yep, this works.  there's another, separate, problem with inlining and
-std=gnu99 but it can be fixed anytime.

they may not have rebuilt prelink against newer libelf yet and thus didnt
notice

0.131-r1 in the tree using __off64_t
