I am working on a port of a Linux kernel module to FreeBSD. I decided to
rebase on FreeBSD 9.1-BETA1. I installed Gentoo Prefix so that I would
be able to work on this port in a more familiar development environment.
Unfortunately, there is an issue where /usr/src/sys/conf/kmod.mk invokes
xargs with -J, which Gentoo Prefix's GNU xargs does not support. I have
written a patch for kmod.mk that will attempt shell substitution in
place of xargs when the current command that relies on xargs fails.
There are probably other ways of addressing this, but I just would like
this to work without requiring a patch to the system sources.
