I get this message with no line number or other indication of =where=. Is
it saying that I left a texture out or something, and where might I find it?

It usualy occurs when you are creating objects with CSG operations and
forget to attach a pigment to one of them. Sometimes they are easy to
locate and other times they can hide rather effectively. I've been using
the program for few years now and still get that warning on occasion.
For example this should cause a warning like you are seeing:
intersection {
sphere { <0,0,0>,1 pigment { rgb 1 }}
plane { y,0 }
}
As you can see the plane has no pigment so the parser issues a no pigment
warning. You could get around this by specifying a pigment for both objects
or even more effeciently by adding a pigment to the intersection instead.
example:
intersection {
sphere { <0,0,0>,1 }
plane { y,0 }
pigment { rgb 1 }
}
Although it's a basic example it illustrates well what to look for.

Is it possible to specify a default pigment in case one isn't specified? I thought
I saw that once somewhere...

#default {
pigment { rgb <1,0,0>}
}

You should not forget the (now known) bug in povray:
If you apply a material block to each component of a CSG, povray will
(wrongly) report that there's no pigment type given.

I have a gripe with povray that may or may not be related to his question:
It will often want to install itself under a directory called
"C:\POV-Ray_for_Windows\" If you put your scene files one or two levels below
this directory, you are even further stuck. When error messages print out on
the message screen, povray does not let the text wrap around NOR does it allow a
scrool bar for messages far to the right. The result is that the only
information you will get about your fatal error is something like:
Filename C:\POV-Ray for Windows\scene-files\boidscenefile01.pov: You idiot, you
made the mistake of...........

Good example: I use a couple planes for clipping a more complex object.
I'll look for things like that.

I don't have that particular problem because the window is wide enough and
the font small enough. IAC, I have my "work" in a different tree from my
programs. IAK, the output is:
...
Drat, can't select text in the Messages window either. Never mind.

When the message window is open choose --> edit --> copy pane.
This will allow you to copy the visible contents of the message
window into memory.
