Subject: Re: bug#69185: [PATCH master] gnu: ocaml: Update to 5.1.1

From: Marc Coquand <[email-masked]>
Date: Sun, 07 Apr 2024 16:42:18 -0500

Hey everyone,

So I decided to attempt this today, but ran into issues with merlin.

Current version of merlin is built for 5.0, and will break if attempted
to be built on version 5.1.

I tried to build to bump up the version but ran into the error when
building ocaml-merlin-lib, which needs to be upgraded to at least
version 4.11-501.

However, when I tried to do so, I ran into the error.

```
Error: The functor was expected to be applicative at this position
```

And struggled with it for a bit but ultimately couldn't get it to work.

I'm adding the diff in case anyone wants to have another attempt.

I've made some more changes, basically I've replaced all instances of
ocaml5.0 with ocaml5.1.

Cheers
Marc
