Comment (by SaintBol):

 Still have some problems with lftp (using Xcode clang). Will open a
 separate ticket if needed, if it's specific to this port...

 Some logs:
 :info:build lftp_ssl.cc:783:47: error: invalid application of 'sizeof' to
 an incomplete type 'X509_OBJECT' (aka 'x509_object_st')
 :info:build lftp_ssl.cc:789:5: error: use of undeclared identifier
 'X509_OBJECT_free_contents'; did you mean 'X509_OBJECT_up_ref_count'?
 :info:build lftp_ssl.cc:795:10: error: member access into incomplete type
 'X509_OBJECT' (aka 'x509_object_st')
 :info:build lftp_ssl.cc:1214:43: error: member access into incomplete type
 'X509_REVOKED' (aka 'x509_revoked_st')
