["Aaron M. Ucko" <amu@alum.mit.edu>]

Package: libcore-ocaml-dev
Version: 113.00.00-1
Severity: serious
Justification: Policy 7.2

ocaml-textutils FTBFS:

The issue appears to be that libcore-ocaml-dev has an undeclared
dependency on libcustom-printf-camlp4-dev.  Could you please take a
look?

Thanks!
