Hmmm... It worked back in August 2008 when I committed it to HEAD.
ttyname() on Linux works pretty bad. First of all, it tries to
readlink() on a node in devfs. If that fails, it falls back to stat()ing
in /dev, /dev/pts, etc. until a device node is found which shares the
same major/minor number. On FreeBSD we just use FIODGNAME (see
fdevname(3)).

Could you please strace/truss/etc the Linux binary to see what it
exactly does?
