pkgsrc.txt says:

But textproc/intltool/buildlink3.mk was removed two months ago, with
the commit message:

> Sweep pkgsrc and convert packages that included intltool/buildlink3.mk
> to use instead "USE_TOOLS+=intltool".  Remove now unused

However, I tried to use that line while hacking at an Ekiga package,
but it seems not to have the desired effect; the configure script
still detected only the included one.

In any case, the documentation should be updated.
