errors in testsuite



Hello

when checking maxima 5.9.3 with clisp, i get the following errors :

Error summary:
Errors found in /home/michel/download/maxima-5.9.3/tests/rtest14.mac, 
problems:

Errors found in /home/michel/download/maxima-5.9.3/tests/rtest_trig.mac,

The others tests are good. Do you think i can install maxima ?
How can i correct this behavior ?

Best regards
