+* Why does the OpenSSL test suite fail in BN_sqr test?
+
+Failure in BN_sqr test is most likely caused by a failure to configure the
+toolkit for current platform. Run ./config -t and ./apps/openssl version -p.
+Do these platform identifiers match? If they don't, then you most likely
+failed to run ./config and you're hereby advised to do so before filing a
+bug report. If it's ./config itself that fails to run, the it's most
+likely problem with your local environment and you should turn to your
+system administrator (or similar).
