As you mention, PREFIX is only defined in ports/Mk, and it'd
definitely be undesirable to be including any of those files :)

The most robust (but unpleasant) solution would be one of the following:

PREFIX?=/usr/local
PORTSMODULESENV=SYSDIR=${SYSDIR} PATH=${PATH}:${PREFIX}/bin:${PREFIX}/sbin

or the equivalent (and perhaps cleaner, not leaving PREFIX defined)

.if !defined(PREFIX)
PORTSMODULESENV=SYSDIR=${SYSDIR} PATH=${PATH}:/usr/local/bin:/usr/local/sbin
.else
PORTSMODULESENV=SYSDIR=${SYSDIR} PATH=${PATH}:${PREFIX}/bin:${PREFIX}/sbin
.endif

Both of these will respect make.conf's setting of PREFIX.
