I've played with this for a couple of minutes with the following
results:

1. By just loading your code as described (after changing one or two
   pathnames) I could run the examples.

2. Everything seemed to be quite slow and stopped moving as soon as I
   moved the mouse over the window.  This might be due to the code
   being interpreted (see below) or because my laptop's graphics card
   doesn't have proper OpenGL support - dunno.

3. Then I hacked a simple delivery script to deliver the
   "ode-test-gravity" example at level 0.  That worked (as above) and
   resulted in an EXE about 22MB big.

4. Now I tried to increase the delivery level and only then found out
   that most of your code was running interpreted.  (I had thought
   that your load scripts would take care of that.)  I started
   compiling and came across a couple of problems and warnings.[1]

5. I modified enough of the code to compile everything (albeit with
   some warnings) but now the resulting EXE didn't work anymore,
   neither at level 0 nor, of course, at higher levels.

6. FWIW, the (non-functioning) EXE at level 5 was slightly smaller
   than 3.5MB.

I'm willing to try my luck again but to spare me some time it'd be
nice if your code compiled cleanly and worked even in a compiled
state.

[1] You should at least add

      (setf *handle-warn-on-redefinition* nil)

    somewhere because you're defining FLI bindings visible from the
    keyword package.  But there's more.

The laptop has 1.5GB RAM - I hope that's enough for OpenGL... :)

OS is WinXP pro SP2, the device manager says my graphics card is
called "ATI Mobility Fire GL T2".  How can I find out if I have OpenGL
drivers installed?

A size of 20GB or more isn't unusual for delivery level 0.  AFAIU
there's virtually no tree-shaking or whatever done at this level.  See
here

  <http://www.lispworks.com/documentation/lw445/DV/html/deluser.htm>

for all the gory details.

You should use LispWorks' Common Defsystem

  <http://www.lispworks.com/documentation/lw445/LWUG/html/lwuser-175.htm>

or an implementation-independent system definition thingy like ASDF or
MK:DEFSYSTEM.

Edi.

I have a 3.1MB LW executable (delivered at level 4) that talks to a
database, does some not _completely_ trivial calculations, outputs
latex source and calls out to pdflatex to create a nice looking
report.

It's not rocket science, but the users find it a bit more interesting
than "hello world" :)

It is started once for each report generated and terminates after
generating the pdf.  As it is invoked from a semi-public webpage and
runs on a busy webserver, startup times and memory footprint was
important considerations.

Yes, probably.  We do use long-running lisp daemons for a lot of
stuff.  We don't use mod-lisp, instead we have a library for letting
php pages talk to the daemons.

However, this particular program is only used to generate tax forms
for a small minority of our customers.  Even the customers who need it
only need it around the time of year when the tax returns are due.  So
it would be a waste to make it a persistent process running all year.

I did contemplate stuffing it into the daemon which handles the tax
stuff for the majority of our customers, but for various reasons (such
as allowing me to play with delivery options :) ) it ended up a
separate program.

Yes, I've been meaning to take a very much closer look at those when
time permits.  However, we have a biggish body of code for handling
latex documents, and it predates both cl-pdf and cl-typesetting.  It
takes some effort to overcome the inertia. :)
