That's not necessarily fatal - we can patch it to build cdump natively and
then run it on the build machine, although it may indeed be agravation.

It is a clean build - the system unpacks, patches, autoconfs and builds automagically

OK - that's a great help - thanx - now I know where to look. That bit runs
through and creates all the GNUmakfiles OK, but not the depfiles. I'll see
why.

thanx
