valgrind couldn't attach gdb

Hi, I'm using valgrind-1.9.6.20030716-5.i586.rpm for suse 8.2 (it's from supplementary/KDE/.../development), I couldn't attach to gdb. Any idea? ==6451== ---- Attach to GDB ? --- [Return/N/n/Y/y/C/c] ---- y ==6451== starting GDB with cmd: -nw /proc/6451/exe 6451 /bin/sh: line 1: -nw: command not found -- -- Verdi March --
