Bug#969451: coccinelle: use the system pyml library

[Pino Toscano <pino@debian.org>]

Source: coccinelle
Version: 1.0.8.deb-4
Severity: wishlist
Tags: patch

Hi,

coccinelle has a bundled copy of pyml; it is used during the build
because no system pyml is found.
Adding libpyml-ocaml-dev as build dependency and libpyml-ocaml as
dependency does the job: the system version is found and used;
patch attached for this.

That said, I haven't tried checking whether the Python capabilities
still work; the build time test suite passes in the same way as before,
and the existing autopkgtest works. Maybe it would be worth extending
the autopkgtests for this...

Thanks,
