How to selectively rebuild?

[Bob Gustafson <bobgus rcn com>]

In one of the later stages of building and installing garnome-0.27.1, I saw
the following output from 'make install'


[===== NOW BUILDING:    gnome-desktop-1 =====]
        [fetch] complete for gnome-desktop.
        [checksum] complete for gnome-desktop.
        [extract] complete for gnome-desktop.
        [patch] complete for gnome-desktop.
        [configure] complete for gnome-desktop.
        [build] complete for gnome-desktop.
        [install] complete for gnome-desktop.
[user1 hoho2 gnome-desktop]$


Unfortunately, when I looked in /home/user1/garnome, all of the directories
were empty.

I need to rebuild the whole thing. However, I don't want to download all of
the files or redo the edits to selected Makefiles.

How can I benignly whack (the cookies?) so that everything gets rebuilt,
but the downloaded files and Makefiles are not whacked too? - something
like a make clean
