valgrind on BBW?

I'm on a BBW with vanilla Angstrom distribution. Valgrind fails like this:

   root@bboneumh2:~/software# ~/local/bin/valgrind --leak-check=yes ./my_program
   ==13719== Memcheck, a memory error detector
   ==13719== Copyright (C) 2002-2012, and GNU GPL'd, by Julian Seward et al.
   ==13719== Using Valgrind-3.8.1 and LibVEX; rerun with -h for copyright info
   ==13719== Command: ./heat_and_water_meter
   ==13719==

   valgrind: Fatal error at startup: a function redirection
   valgrind: which is mandatory for this platform-tool combination
   valgrind: cannot be set up. Details of the redirection are:
   valgrind:
   valgrind: A must-be-redirected function
   valgrind: whose name matches the pattern: memcpy
   valgrind: in an object with soname matching: ld-linux.so.3
   valgrind: was not found whilst processing
   valgrind: symbols from the object with soname: ld-linux.so.3
   valgrind:
   valgrind: Possible fixes: (1, short term): install glibc's debuginfo
   valgrind: package on this machine. (2, longer term): ask the packagers
   valgrind: for your Linux distribution to please in future ship a non-
   valgrind: stripped ld.so (or whatever the dynamic linker .so is called)
   valgrind: that exports the above-named function using the standard
   valgrind: calling conventions for this platform. The package you need
   valgrind: to install for fix (1) is called
   valgrind:
   valgrind: On Debian, Ubuntu: libc6-dbg
   valgrind: On SuSE, openSuSE, Fedora, RHEL: glibc-debuginfo
   valgrind:
   valgrind: Cannot continue -- exiting now. Sorry.

I've installed libc6-dbg as it says. Same problem.

While installing libc6-dbg, opkg complains like this:

   bash-dbg: unsatisfied recommendation for ncurses-libtinfo-dbg
   libc6-dbg: unsatisfied recommendation for libsegfault-dbg
   libc6-dbg: unsatisfied recommendation for eglibc-thread-db-dbg
   libc6-dbg: unsatisfied recommendation for eglibc-extra-nss-dbg
   libc6-dbg: unsatisfied recommendation for libcidn-dbg

But trying 'opkg install eglibc-thread-db-dbg' says its an unknown
package.

Any clues?

Thanks,
