[erlang-questions] openssl cipher disabled

I'm trying to compile 17.1 on a system that has obsolete ciphers disabled, such as RC2.  I get the following error

In file included from crypto.c:51:
/usr/include/openssl/rc2.h:64:2: error: #error RC2 is disabled.

It appears the function rc2_cbc_encrypt/3 can't compile.  Can these functions be disabled based on the available ciphers in a hardened system?
