Dear powerpc- and s390 porters,currently, the unace-nonfree package has status Not-For-Us on your archs and is thus not auto-built. However, the recent package revision 2.5-7 contains a fix in the endianess detection code that should make it possible to build it on your archs. Please remove the Not-for-Us status of this package and trigger compilation on the autobuilds.
Thanks, Fabian
