Comment (by nh2):

 I think the problem for 2) is that if `dblatex` is not found in the
 `PATH`, but the instructions

 {{{
 $ cat > mk/build.mk <<EOF
 V=1
 HADDOCK_DOCS=YES
 LATEX_DOCS=YES
 HSCOLOUR_SRCS=YES
 BUILD_DOCBOOK_HTML=YES
 BUILD_DOCBOOK_PDF=YES
 BUILD_DOCBOOK_PS=YES
 BeConservative=YES
 EOF
 }}}

 force `BUILD_DOCBOOK_PS`/`BUILD_DOCBOOK_PDF` to `YES`, then `configure`
 doesn't check that `dblatex` is actually available, and happily goes on
 with `DBLATEX` and `DblatexCmd` being set to `""`.

 I think `configure` should check that `dblatex` is actually available, or
 `DblatexCmd != ""`.
