pandoc-lua can't require binary packages when installed with Conda

Explain the problem.

This is a weird issue. I've been trying to switch to more isolated workflow, using local environments of tools, and in this case used a conda manager pixi to install lua luarocks and pandoc local to a working folder. I used luarocks to install a lua debugging package mobdebug. Given a minimal test.lua script:

md = require("mobdebug")

print("Hello World")

Run with lua it is ok:

ζ lua test.lua 
Hello World

but run with pandoc-lua, a mapping process and mapped file (non-platform) have different Team IDs error occurs:

ζ ➪ pandoc-lua test.lua
Error running Lua:

This error only occurs for compiled libraries, pure lua code requires are ok. Something in the way pandoc is compiled increases the security level of the bundled lua. I thought I'd report this edge case for visibility than imagining it could be fixed.

Pandoc version?
V3.3 on macOS 14.6

See also #6850. A PR to clear that up in the docs would be greatly appreciated.

Thanks @tarleb -- this is quite a messy issue to document, the current reference to this in the docs is only for the statically-linked linux build, and my issue was on a conda-built binary for macOS. I wonder if a note right at the top under Installing pandoc for statically-linked builds in general then referenced by each OS?

[iandol]

I also wonder whether it is worth mentioning the fact that Conda can be used to install pandoc is worth adding to that doc as well?

[tarleb]

Adding Conda as another install option would be good, I think 👍

Good idea. Would you have time to create a PR?

[iandol]

Yes, I can do this.
