Ugh, sorry about that, I completely forgot about removing stale patch.

Hmm, `make install clean' is a dangerous command, your system may be
left broken without a clue :)

/bin/mv and /usr/bin/chflags are both statically linked, so
I expect that they worked for you(unless you wanted to read the man page).

I expect that both patch and build of rtld-elf failed. When I tested it,
the patch failed because of a conflict in Makefile(echo $? after patch
gives you `1'), and build fails because of some missing symbols.

Thanks for the warning. I think that a workaround with LD_LIBRARY_PATH
is still usable, if not perfect, until our native support for name space
translation is implemented in rtld.
