No, except the KERNCONF entry it's exactly the same :

# General settings.
KERNCONF=Melon
MASTER_SORT?= .fr .uk

# Portconf.
.if !empty(.CURDIR:M/usr/ports*) && exists(/usr/local/libexec/portconf)
_PORTCONF!=/usr/local/libexec/portconf
.for i in ${_PORTCONF:S/|/ /g}
${i:S/%/ /g}
.endfor
.endif

# Perl.
PERL_VERSION=5.10.1

# No need modules.
NO_MODULES=yes

# Specify other directories.
WRKDIRPREFIX=   /usr/obj
DISTDIR=        /usr/distfiles
