[Bug]: Neovim v0.11.2-1 Fails with "Permission denied" from /libexec/nvim + Repeated makewhatis Warnings!!

[Chandramauli-Arm64]

Problem description

After updating to Neovim v0.11.2-1 on Termux (Android 15), launching nvim, vi fails with:

exec: /data/data/com.termux/files/usr/libexec/nvim: Permission denied

The previous version, v0.11.1, worked flawlessly under the same environment.

What steps will reproduce the bug?

• Update or install neovim.

• Run any of the following:
  nvim or vi

• Observe error:
  /data/data/com.termux/files/usr/bin/nvim: 13: exec: /data/data/com.termux/files/usr/libexec/nvim: Permission denied

• Manually executing the full binary works fine:

/data/data/com.termux/files/usr/libexec/nvim/nvim

• Here is the output what I got after updating packages:
  update-alternatives: using /data/data/com.termux/files/usr/bin/nvim to provide /data/data/com.termux/files/usr/bin/vim (vim) in auto mode
  update-alternatives: warning: failed to detect 'makewhatis', not updating manpage database

  update-alternatives: warning: failed to detect 'makewhatis', not updating manpage database
  update-alternatives: using /data/data/com.termux/files/usr/bin/nvim to provide /data/data/com.termux/files/usr/bin/vi (vi) in auto mode
  update-alternatives: warning: failed to detect 'makewhatis', not updating manpage databases

What is the expected behavior?

• nvim or vi should invoke the correct Neovim binary without Permission denied.

• makewhatis errors should not appear if manpage handling is not in use (Termux typically omits them).

Already working on it.
Missed a path change in the last revision.

Still need to look into the makewhatis errors.
(This is what I get for merging at 4am)

Waiting 👀👀

I'm not sure why makewhatis isn't available for you.

We do ship man pages for packages that offer them, you can install mandoc for the man page database to be properly updated when installing packages (note this may take a while on the first indexing)

Okay I will try it.

CC: @robertkirkman since you wrote that dpkg hook, do you have anymore insights here other than mandoc isn't installed?
Also would it make sense for the hook to suggest installing mandoc if makewhatis isn't found?

Okay. Installed Mandoc as per your say and for the pr you were working on is merged. So, I am waiting for the update. 👀
