Are you sure it's not actually PBKDF2-HMAC-SHA512 you need?
The format for that is:
$pbkdf2-hmac-sha512$<num_iterations>.<hex_salt>.<hex_hash>
For example:
$pbkdf2-hmac-sha512$1000.6b635263736c70346869307a304b5276.80cf814855f2299103a6084366e41d7e14f9894b05ed77fa19881d28f06cde18da9ab44972cd00496843371ce922c70e64f3862b036b59b581fe32fc4408fe49
The number of iterations is given in decimal, not hex.
