requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.

Since you only requested a single operation it is extremely likely that
the package is simply not installable and a bug report against
that package should be filed.

Here is the proposed patch for hardy-updates:

pycaml (0.82-7ubuntu0.1) hardy-proposed; urgency=low

  * Fix FTBFS (and thus make the package installable again) by backporting
    a patch from pycaml 0.82-8 (LP: #197216).
  * Apply fix from Debian OCaml Group SVN (rev 5688):
    + Add missing dependency on ocaml-interp to pycaml.
    + Move dllpycaml_stubs.so to the directory where ocaml looks for it.
  * debian/Makefile:
    + Build with python 2.5.
  * debian/control:
    + Modify Maintainer value to match DebianMaintainerField spec.

The patch contains two fixes: one for the FTBFS of pycaml with python 2.5 (patch taken from pycaml 0.82-8) and a second fix for a problem I discovered while testing the rebuild package. I've contacted the Debian OCaml maintainers for help and they fixed it in their SVN where I took the fix from.

TEST CASE:
- try to install pycaml in hardy

The second problem is harder to test as it needs a package where only the first fix got applied. But with the fixed package it's possible to run pycamltop (included in pycaml) without getting errors about missing files.

ACK from motu-sru.

[Michael Bienia (geser)]

Both problems are also fixed for intrepid.

Accepted into -proposed, please test and give feedback here

+1

- pycaml from hardy fails to install
- pycaml from hardy-proposed installs fine
- pycamltop runs (gives a prompt #)
- during the test of pycamltop I had inotifywatch running on /usr/lib/ocaml/3.10.0/stublibs/dllpycaml_stubs.so. It showed the file was opened, accessed and closed. So apparently pycamltop looks for the file and finds it in the correct directory.

Tested (on AMD64) now with the package build by the buildds.
