Hi Iain,

This only works with a limited number of libraries, and in that
instance you can use PREFER_PKGSRC=no in your mk.conf to ensure that
the builtin versions are used.

If you are bootstrapping, use '--prefer-pkgsrc=no' to automatically
put this into mk.conf.

To see whether a package supports this, check that there is a file in its pkgsrc directory.  This generally only works
with libraries, it doesn't work for e.g. python as there are too many
issues with doing that.
