I have seen a few topics about user having difficulty getting snmpd to run because it was compiled with dependencies to pcilib.
I managed to compile it:
First make sure the package pcilib was not installed in then system, then using abs I edited PKGBUILD:
changed the line: arch=('i686' 'x86_64') to arch=('arm')
changed the line depends=('openssl' 'libnl' 'pciutils') to depends=('openssl' 'libnl' )
net-snmp only creates a dependency on pciutils only If the package exists
It does not make sense to have it on so it would good if the dist maintainer removes it form raspi and other arm devices.
Included the package I compiled on my raspi
