 * `make test` creates a test binary that is intended to be run against `mtest`. `mtest` can be built with `make mtest` and test execution is done like `./mtest/mtest | ./test`. `mtest` is creating test vectors using an alternative MPI library and `test` is consuming these vectors to verify correct behavior of ltm
 * `make test_standalone` creates a stand-alone test binary that executes several test routines.

 It will skip the tests for `long double` and prints a reminder to compile and run the tests without that flag to assure numerical correctness.
 
+In case your platform doesn't provide Valgrind at all and the auto-detection fails, please build `test.c` with the additional compiler flag `-DLTM_NO_VALGRIND`, e.g.:

 ## Building and Installing
 
 Building is straightforward for GNU Linux only, the section "Building LibTomMath" in the documentation in `doc/bn.pdf` has the details.
