Well that's completely wrong is why... You are trying to exec the wrong executable and have merged several arguments into one. You want:

execlp("/path/to/valgrind", "valgrind", "--tool=callgrind", "/usr/local/pmas/bin/pma", "-n", option_pma_name, NULL);

So you are running valgrind, and providing the arguments that valgrind needs including the path to the program it needs to start.
