ld: fatal: Symbol referencing errors when compiling with snmp

Below is output from debug.log. Also, I tried configuring with and without --enable-sysvsem --enable-sysvshm, and --enable-ucd-snmp-hack. If I remove --with-snmp=/usr/local, configure completes successfully. Thanks in advance for any help.
