There is an environment variable called VALGRIND_LIB
This can be set to point to teh base directory of where the tools are.

Valgrind do not document the workaround very well imho
see http://valgrind.org/docs/manual/dist.readme-developers.html


For my cluster:
$ export
VALGRIND_LIB= \
/opt/opens/VALGRIND_OPENS/valgrind_opens-3.4.1_Bull.9010/lib/valgrind/ 

hence:
/opt/opens/VALGRIND_OPENS/valgrind_opens-3.4.1_Bull.9010/bin/valgrind /bin/ls
