Where's linux-mirror.org coming from?

[Anton Shterenlikht]

I maintain math/slatec.
I see in http://people.freebsd.org/~ehaupt/distilator/math/slatec/

In my port I have

MASTER_SITES=   NL:slatec,blas

which, according to bsd.sites.mk, does not
include linux-mirror.org. In fact I can't
find it in bsd.sites.mk at all.
So where is it coming from?

Thanks
