Looking through the validation log I see that tests fail with this error message:

Actual stderr output differs from expected:
--- /dev/null	2013-05-14 15:38:10.771000000 +0200
+++ ../../libraries/base/tests/IO/T3307.run.stderr	2013-05-15 09:21:45.695049002 +0200

+WARNING: cache is out of date: /dane/uczelnia/projekty/ghc-validate/bindisttest/install

*** unexpected failure for T3307(normal)

Any ideas why this happens?
