TestFailed at TrueCrypt::EncryptionTest::TestXts:831

I should've seen it coming: apparently, TrueCrypt is not working under Snow Leopard, at least not under 64 bit:

$ system_profiler SPSoftwareDataType | grep 64-bit
      64-bit Kernel and Extensions: Yes
$ TrueCrypt --text --test
Error: TestFailed at TrueCrypt::EncryptionTest::TestXts:831
There's a way to create (encrypted) volumes with Disk Utility.app, but I fail to see how we can use a whole blockdevice as a backing store...

Update: Truecrypt 6.3 is out and even works on 64bit MacOS 10.6 now. However, MacFUSE does not but there's a workaround to fix this.
