I'll peek into those config files tonight to see what I got (and I'll
try to reproduce the problem).
Last weekend I ended up in getting an i686 DateTime.o
my dev sys is opensuse 11.3 on 686, target was sheevaplug, but I seem
to recall it also appeared for beagleboard.
distro minimal.

I have only seen the problem with the two recipes I mentioned. Both of
these use Build.PL. I have not seen it with packages that have a
Makefile.PL (which seems to be the majority), but if it fails again
tonight with the patch I'll recheck that too.

Frans.
