That's how it should be. But it might not necessarily be always the
case, especially with Experimental add-ons for a distro.

By "Experimental" I mean the Experimental channel available in Debian
(http://wiki.debian.org/DebianExperimental). libpng is up to version 1.5.11 and
libpng-dev is matching (1.5.11).

Quote from that web page: "This directory contains packages and tools
which are still being developed, and are still in the alpha testing
stage. Users shouldn't be using packages from here, because they can be
dangerous and harmful even for the most experienced people."
Given this statement, I'm very much inclined to blame the problems on
the experimental status of the libpng 1.5.11 Debian package, so my
proposed solution is to run POV-Ray on a Debian stable distribution,
and/or contact the people responsible for the libpng 1.5.11 Debian
package for support (and/or to inform them that they /may/ have a
problem there).
(That said, I guess I'll have a look at Debian experimental myself; no
promise though.)

I will see what happens if I install both libpng and libpng-dev from unstable
(as you suggest, it may just be a packaging problem on their end).

I found out that I have more serious problems (parts of boost are missing) - I
will rectify those and report back. Reverting to libpng12 got rid of the libpng
error.

This issue has now been rectified. I reverted to libpng12 and installed the
missing boost libraries. POV-Ray then compiled fine. As an aside, does anyone
know how to change the number of render threads?

Yes.
ok, the option is -WT<number>
and it should be in the wiki-doc, I hope so.

Thanks - the manpage hasn't been updated, but I checked the docs. Also, it
should be +WT (I think...that's what the docs said IIRC). Anyway, this issue is
closed. Thank you everyone for helping me with this problem!
