This is a wild guess due to lack of good information, but it sounds like 
your snmp libraries are set up to require some external crypto library, 
probably openssl.

Try adding --with-openssl=<where ever your openssl libs are, probably 
/usr/lib> to your configure


If that doesn't work:

What OS are you building on?

What version of ucd-snmp or other snmp package do you have?

Do you have openssl installed?
