Thank you for the explanation.  As for building the FreeBSD/arm Poudriere jail on a 10-STABLE system, unfortunately that no longer appears to work for me.  It fails when building the native-xtools.

I think this package building issue is probably a gentle hint that I should also upgrade my 10-STABLE armv6 systems (Raspberry Pi) to 11-CURRENT, like my BeagleBone Black.  It's probably better in the long run than trying to figure out how to build 10-STABLE packages, as 11-CURRENT appears to be where all the focus and TLC is in the FreeBSD/arm world nowadays.  Plus, I'd only have to maintain one local FreeBSD/arm package repository... :-)

Cheers,

Paul.
