Poudriere, pkgng and "has to be built manually"

[J David]

Hello,

When attempting to build the port lang/racket under poudriere, the
following message is generated:

====>> Ignoring lang/racket: has to be built manually: i386 requires
kern.maxdsiz="640M" to build

This is on a machine with kern.maxdsiz=32G.

What is the best way to build this package so that it winds up in the
poudriere-generated pkgng repository index, and so that it is
preserved during future runs of poudriere?

Thanks!
