Hello

We have our product covering with Postpotter's clay 10 without problems.
We have compiled the product to work with Postpotter's clay 15 and on having executed it, it has given us an error: dlopen: : undefined symbol: pg_hmac_free
I understand that he does not find the function pg_hmac_free
From our code, we are not calling to any function of pg_hmac. It must be some internal code.
We have checked in what place it can be that it is called, and do not find it.

If you can help me it would be brilliant

Thank you very much
