I tracked it to the fact that Nixpkgs had GTK-Doc 1.11 whereas
gktdoc-mkpdf is more recent.  I upgraded to 1.15, which fixed the
problem.

Besides, Nixpkgs wraps ‘aclocal’ so that it searches for m4 files in
$ACLOCAL_PATH:

  
https://svn.nixos.org/repos/nix/nixpkgs/trunk/pkgs/development/tools/misc/automake/builder.sh

However, those extra -I flags are passed *before* the user flags (see
<https://svn.nixos.org/repos/nix/nixpkgs/trunk/pkgs/build-support/make-wrapper/make-wrapper.sh>),
which is presumably the reason why your gtk-doc.m4 was ignored.
Probably worth a fix.

Thanks,
Ludo’.
