thanks Viktor,
but what if (for reasons beyond this discussion) I wish to use the low
level internal aesni_* functions?

Would I have to compile libssl-dev myself ?

It looks to me as if Debian was trying to protect me from myself.
Can't I play with the internal functions ? I don't mind loosing
compatibility on non-AES-NI processors.
