Test-Simple - Thread tests fail with 'lock can only be used on shared values'

Thread tests fail with 'lock can only be used on shared values'
When building Test-Simple-0.64:
perl Makefile.PL make make test

several threading related tests fail, e.g.:
--------- t/threads.................Thread 1 terminated abnormally: lock can only be used on shared values at + /home/florian/tmp/Test-Simple-0.64/blib/lib/Test/Builder.pm line 394. Thread 2 terminated abnormally: lock can only be used on shared values at /home/florian/tmp/Test-Si +mple-0.64/blib/lib/Test/Builder.pm line 394. Thread 3 terminated abnormally: lock can only be used on shared values at /home/florian/tmp/Test-Si +mple-0.64/blib/lib/Test/Builder.pm line 394. Thread 4 terminated abnormally: lock can only be used on shared values at /home/florian/tmp/Test-Si +mple-0.64/blib/lib/Test/Builder.pm line 394. Thread 5 terminated abnormally: lock can only be used on shared values at /home/florian/tmp/Test-Si +mple-0.64/blib/lib/Test/Builder.pm line 394. lock can only be used on shared values at /home/florian/tmp/Test-Simple-0.64/blib/lib/Test/Builder. +pm line 1352. # Looks like your test died before it could output anything. t/threads.................dubious Test returned status 255 (wstat 65280, 0xff00) DIED. FAILED tests 1-6 Failed 6/6 tests, 0.00% okay ---------
I tried to find solutions for this prob on many newsgroups, google, etc, however just found a couple of similar reports, but no solutions. Please find perl information below, I would appreciate it very much if somebody could help me here, since it's a complete show stopper for my project currently.
