Hi Raphael,

Ok, so this is the kind of feedback I've been hoping to hear for some

I'll have to read up on this.  I'm somewhat fuzzy on how this stuff is
normally handled.

This is easy to add.

I actually do have DESTDIR support.  Let me know if it isn't using the
path appropriately.  Be sure to check the trunk version.  I'm not sure
if the latest release has this.  In general, let's work off of the
trunk until you're satisfied with my build script.

What environment variables are used to specify architecture-specific
paths?  If CC, CFLAGS, LDFLAGS and the like are all accepted properly,
what else would you need for cross-compiling?

Ok, I'll look into this.

Does my uid check not work for you?

I find make to be awful.  I've been using it off and on for years, but
I've decided it is antiquated.  SCons has nice advantages (you know it
is actually portable), though it can certainly use more work.  I find
that guide you linked to is just a tad rigid and closed-minded about
using alternative tools.  Let's just get SCons working like Debian's
build scripts expect.  SCons just runs python scripts afterall, so it
can't be that hard to make it accept whatever inputs you need it to.

Besides what you mentioned above, I see the guide mentions in passing
a variety of other environment variables that should be accepted:

 "If you choose to use SCons anyway, please ensure that the usual
environment compiler variables (CC, CFLAGS, ...) and path variables
(DESTDIR, BINDIR, LIBDIR, ...) are honoured. There is a recipe, that
addresses some of these."

It would be *great* of *all* environment variables were listed
somewhere, instead of just a few and a hand wave... =P  Let me know if
you have a more complete reference somewhere.

thank you!
