Bug#898173: planets: you can't use ${ocaml:Depends} in architecture:all packages

[Sergei Golovan <sgolovan@nes.ru>]

Package: planets
Version: 0.1.13-18
Severity: grave
Justification: renders package unusable

Dear Maintainer,

The planets package 0.1.13-18 uses ${ocaml:Depends} substitution variable
in debian/control. It would be great if the package were
architecture-dependent. But since it isn't, the debian/control now contains
dependency on virtual liblabltk-ocaml-l9fi9 picked from an amd64 arch,
and can't be satisfied on any other arch (on i386 it's liblabltk-ocaml-pc510
for example).

That's why it can't still be in testing despite of more than 3-month delay.
