Valgrind and apr help

This problem is probably best answered by Philip since he uses
valgrind all the time.

I didn't use to have this problem with valgrind, but now I do.

Trying to find a core dump in time-test:

% cd subversion/tests/libsvn_subr/.libs
% ./lt-time-test
PASS: lt-time-test 1: test svn_time_to_cstring
PASS: lt-time-test 2: test svn_time_from_cstring
PASS: lt-time-test 3: test svn_time_from_cstring (old format)
PASS: lt-time-test 4: test svn_time_[to/from]_cstring() invariant
Segmentation fault (core dumped)
% valgrind ./lt-time-test
version `GLIBC_2.1.1' not found
(required by /opt/i386-linux/installed/apache-2.1-cvs-2004011900/lib/libapr-1.so.0)

It looks like it also happens with apr. Trying to run valgrind on
apr's testall program gives me this output:

% cd srclib/apr/test
% valgrind ./testall
./testall: /opt/i386-linux/installed/valgrind-2.1.0/lib/valgrind/libpthread.so.0:
version `GLIBC_2.1.1' not found (required by

This is with valgrind 2.1.0 on RedHat 9 with apr and apr-util
compiled inside httpd-2.1.

Ldd shows that pthread is linked against /lib/tls/libpthread.so.0.
instead of
% ldd testall
