It really depends of which libc you use, and if you have the right algorithm present. If MD5 and DES are not present, them it is expected.

Please try using PHP 5.3 snapshot, all algorithms are now available, no matter which libc you use (or not).

Well, it's not a PHP-Bug, but a php5-suhosin bug in the version 0.9.22. This bug is fixed in 0.9.23. see: http://www.hardened-php.net/suhosin/changelog.html

You don't need suhosin extension anymore to solve crypt's issues (the patch itself is still fine) as we use the same blowfish implementation (from Solar Designer/openwall) and everything is enabled by default when the system is outdated. However it is still not a bug  > bogus
