I had a similar problem installing Kerberos5 on mountain lion with several other ports installed (incouded OopenSSL). "... ---> Building kerberos5 Error: org.macports.build for port kerberos5 returned: command execution failed Error: Failed to install kerberos5 Please see the log file for port kerberos5 for details: /opt/local/var/macports/logs/_usr_local_var_macports_sources_rsync.macports.org_release_tarballs_ports_net_kerberos5/kerberos5/main.log" Looking at logs and sources, I got: pkinit_crypto_openssl.c: In function ‘decode_data’: pkinit_crypto_openssl.c:3662: error: too many arguments to function ‘EVP_PKEY_decrypt’ Actually and old post https://trac.macports.org/ticket/25816 <https://trac.macports.org/ticket/25816> suggested to add the last parameter buf_len in function called at the same line 3662. I just removed this parameter snf the file and the all project get compiled correctly. Is this the right solution ?
