The way net-snmp installed pkg also activated it without doing a pkg2ng;
since this happened
in the middle of a portupgrade part of the portupgrade kept its records
the old way and the rest
the new way without any of the old ports in the database.  This made a
lot of things build twice.
Not very nice...

No, the way I read the makefile lines in question it installed it if it
wasn't already
installed..  See:

# pkg-1.2 cannot handle this dependency well.
.if !defined(WITH_PKGNG)
LIB_DEPENDS=    libpkg.so:${PORTSDIR}/ports-mgmt/pkg
.endif

This will install if it is there or not, but only if it is NOT in use. 
Probably not what was
intended.
