Yes, I don't think that's a good thing to make openssl installation

In light of this discussion, it seems to me that we still want at the
end the --allow-weak-keys anyway as an extreme fallback, and this even
if there is additional support for prngd. An essential part is to
document the weakness of this option properly, like not using pgcrypto
with that if there is no other entropy source on an OS. By reading
this thread, the point is that we should not complicate the support
for obscure nix platforms, and it would be user-unfriendly to require
users to install prngd to get more entropy from the system.
And actually, enabling prngd would need to be controlled by a
configure switch as well disabled by default, no?
