If you don't mind installing a small module, capture from IPC::System::Simple works pretty well in my experience:

use IPC::System::Simple qw/capture/;
my $snmp_trap = capture '/usr/bin/snmptrap', '-v', '2c',
  '-c', 'public', '127.0.0.1', '', '.3.5.6.1.4.7.34566.12343.897.0.2';

(I hope I got the args you're trying to pass correct.)

Otherwise, open would work too, although it's not as concise (e.g. open my $fh, '-|', @command or die $!; and then reading from $fh).
