hurd does not compile

[Peter Baumgarten]

So as the title suggests hurd from git.sv.gnu.org/hurd/ does not compile
for me, but hurd-0.5 from ftp.gnu.org/gnu/ does.  The message I am
getting is 

~/hurd/exec/exec.c:1173: undefined reference to `task_set_name'
collect2: error: ld returned 1 exit status
make[1]: *** [exec] Error 1
make[1]: Leaving directory `/home/me/hurd/exec'
make: *** [exec] Error 2

can anyone tell me what is going on with this error message? I am
compiling this in a debian hurd qemu image. If you respond could you
also include your IRC nick is so I can bug in the chatroom, mine is
Petroz.
