Bug#709853: gd4o: FTBFS: Cannot mkdir .../debian/tmp//usr/lib/ocaml/gd

["Aaron M. Ucko" <ucko@debian.org>]

Source: gd4o
Version: 1.0~alpha5-6
Severity: serious
Justification: fails to build from source (but built successfully in the past)

Builds of gd4o covering only its architecture-dependent packages (as
on the autobuilders) have been failing:

  files=$( for f in gd.cma gd.cmxa dllocamlgd.so libocamlgd.a *.mli *.cmi gd.a META; do if [ -f "$f" ]; then echo $f; fi; done; ) && \
  	 ocamlfind install   gd $files
  ocamlfind: Bad configuration: Cannot mkdir /.../gd4o-1.0~alpha5/debian/tmp//usr/lib/ocaml/gd because a path component does not exist or is not a directory
  make[1]: *** [install] Error 2

Could you please ensure the presence of debian/tmp/usr/lib/ocaml,
either by (recursively) creating it explicitly or by listing it in an
architecture-dependent package's .dirs file?

Thanks!
