This is libpthread.so's obscure way of saying "There are multiple
thread libraries linked to this executable".  It really should print a
better error message (or better yet, coordinate with the other thread
libs so this error doesn't even show up).  Run ldd -a on the binary and
find out if there are any shared libs depending on libc_r.
