Openvpn2 +pkcs11 Variant Fails to Build - use of undeclared identifiers 'CK_RSA_PKCS_PSS_PARAMS' and 'pss_params'

[RobK88]

I am unable to build openvpn2 +pkcs11 variant on Lion and on High Sierra with the same errors. It looks like the +pkcs11 variant is broken.

When trying to install with the -v option, one sees:

I have attached main.log for more info.

I also tried compiling using clang-15 but it also fails.
