        ===>  Building for hmake-3.08
        cd src/hmake;          gmake HC=ghc install config
        gmake[1]: Entering directory
        `/usr/obj/ports/hmake-3.08/hmake-3.08/src/hmake'
        mkdir -p /usr/obj/ports/hmake-3.08/hmake-3.08/targets/sparc-OpenBSD/obj/hmake || /usr/bin/true
        ghc    -package lang -c -o
        /usr/obj/ports/hmake-3.08/hmake-3.08/targets/sparc-OpenBSD/obj/hmake/QSort.o
        QSort.hs ghc    -package lang -c -o
        /usr/obj/ports/hmake-3.08/hmake-3.08/targets/sparc-OpenBSD/obj/hmake/Unlit.o
        Unlit.hs
        ...

The second file to be built.
