Hi.

I am trying to install kamailio 4.4.2 on ubuntu xenial, for use with kazoo.
Using source and compiling just went fine, but 
/usr/local/sbin/kamailio -c
throws
ERROR: <core> [sr_module.c:582]: load_module(): could not open module </usr/local/lib64/kamailio/modules/outbound.so>: /usr/local/lib64/kamailio/modules/outbound.so: undefined symbol: EVP_sha1

any hint appreciated!

Thanks,
Christian
