Net::SNMP version 4.1.2 has some perl module dependcies (from the Makefile.PL):

   PREREQ_PM     => {
      Crypt::DES   => '2.03',
      Digest::MD5  => '2.11',
      Digest::SHA1 => '1.02',
      Digest::HMAC => '1.00'
   },

however it implements SNMP in pure perl so it has no requirements for the any external SNMP libraries.
