#               given with --prefix.

Please consider configuring with the flag --unified .
It's to test out a new "unified" building system.

One cool feature is that you can have your build directory elsewhere,
for example:

    make clean          # Clean the current configuration away
    mkdir $plausible_builddir
    cd $plausible_builddir
    $plausible_to_sourcedir/config --unified
    make
    make test

Please report any problem you have.
