True. It's also not the ones I use on the jails:

	[/usr/ports/devel/cmake] root at build3>cat /etc/make.conf
	[/usr/ports/devel/ccache] root at build3>cat /etc/make.conf
	WRKDIRPREFIX=           /var/ports
	DISTDIR=                /var/ports/distfiles
	PACKAGES=               /var/ports/packages
	PACKAGE_BUILDING=       yes
	FTP_PASSIVE_MODE=       yes

	.if !defined(NOCCACHE)
	CC=/usr/local/libexec/ccache/world-cc
	CXX=/usr/local/libexec/ccache/world-c++
	.endif
