Blind in one eye, could not see out the other: I thought I had listed the warnings - they were above:
configure: WARNING: libattr development library was not found or not usable.
configure: WARNING: GNU coreutils will be built without xattr support.
configure: WARNING: libcap library was not found or not usable.
configure: WARNING: GNU coreutils will be built without capability support.
configure: WARNING: libgmp development library was not found or not usable.
configure: WARNING: GNU coreutils will be built without GMP support.
For the rest, I would rather not know the itty-gritty. My main reason for coreutils is because of the differences between AIX install, bsd install and coreutils install. coreutils version works where AIX and bsd fail.
