after problems installing all test in once i was trying to download tests individualy.

./phoronix-test-suite install x11perf
PHP Notice: Use of undefined constant STDIN - assumed 'STDIN' in /home/scratch/mnt/phoronix-test-suite/phoronix-test-suite/pts-core/functions/pts-functions-install.php on line 349
PHP Warning: fgets(): supplied argument is not a valid stream resource in /home/scratch/mnt/phoronix-test-suite/phoronix-test-suite/pts-core/functions/pts-functions-install.php on line 349

it seems not to be serious but why does it show up anyway ?
