[Debian-med-packaging] Bug#1151959: src:mcl: fails to migrate to testing for too long: FTBFS on loong64: /usr/bin/ocamlopt not found

[Paul Gevers]

Source: mcl
Version: 1:22-282+ds-4
Severity: serious
Control: close -1 1:22-282+ds-5
Tags: sid forky
User: release.debian.org at packages.debian.org

[Manual note to the template below: it seems that re-enabling the ocaml 
bindings failed the build on loong64. As a stop gap work around, maybe 
don't build the binding until a solution has been found.]

Dear maintainer(s),

The Release Team considers packages that are out-of-sync between testing 
and unstable for more than 30 days as having a Release Critical bug in 
testing [1]. Your package src:mcl has been trying to migrate for 31 days 
[2], hence this bug report. The current output of the migration software 
for this package is copied to the bottom of this report and should list 
the reason why the package is blocked. Regularly, reporting issues 
against reverse (build/test/regular) dependencies is what needs to 
happen. If this has already been done, than this bug is just for 
tracking purposes.

If a package is out of sync between unstable and testing for a longer 
period, this usually means that bugs in the package in testing cannot be 
fixed via unstable. Blocked packages can have impact on other packages, 
which makes preparing for the release more difficult. The situation that 
caused this bug report might even be the result of such an issue. We 
expect maintainers to fix issues that hamper the migration of their 
package in a timely manner. If your package in this situation due to 
another package, consider helping out.

This bug will trigger auto-removal when appropriate. As with all new 
bugs, there will be at least 30 days before the package is auto-removed.

This bug submission immediately closes the bug with the version in 
unstable, so if that version or a later version migrates, this bug will 
no longer affect testing. This bug is also tagged to only affect sid and 
forky, so it doesn't affect (old-)stable.

If you believe your package is unable to migrate to testing due to 
issues beyond your control, don't hesitate to contact the Release Team.

This bug report has been automatically generated. If you have any 
comments with regards to the content or the process, please reach out to me.

Paul
