undefined symbols in /lib/libthread_db.so.1

[Jack Howarth <howarth@bromo.msbb.uc.edu>]

   Anyone else using debian glibc cvs to build glibc 2.3.2-1?
Do you see the following as well...

ldd -r /lib/libthread_db.so.1
        libc.so.6 => /lib/libc.so.6 (0x0fe80000)
        /lib/ld.so.1 => /lib/ld.so.1 (0x08000000)
undefined symbol: ps_pglobal_lookup     (/lib/libthread_db.so.1)
undefined symbol: ps_pdwrite    (/lib/libthread_db.so.1)
undefined symbol: ps_lsetfpregs (/lib/libthread_db.so.1)
undefined symbol: ps_getpid     (/lib/libthread_db.so.1)
undefined symbol: ps_lsetregs   (/lib/libthread_db.so.1)
undefined symbol: ps_pdread     (/lib/libthread_db.so.1)
undefined symbol: ps_lgetfpregs (/lib/libthread_db.so.1)
undefined symbol: ps_lgetregs   (/lib/libthread_db.so.1)

This is on debian ppc sid and I am trying to puzzle out
which shared lib is providing these symbols.
