[bug#59355] [PATCH] gnu: Add dataparksearch.

Hi Adam,

Thanks!  I've applied the patch locally but stopped short of 
pushing.  I have several questions and [notes]:

> +(define-public dataparksearch
> +  (package
> +    (name "dataparksearch")
> +    (version "4.54-2016-12-03")

I don't think this tag is anything special compared to other 
commits.  Is it?

There are many more recent commits, up to 2022.  If the argument 
is ‘4.53 is ancient’ (it is!), should we just package the latest 
commit?

Would the latest release (4.53) instead still be useful today?

[All checked into Git.  Nice.  This snippet is ‘ugly’ because it 
addresses an ugly problem.  I think I'll keep it but add an 
apologetic comment.]

[We don't dangle brackets like this but keep them on the previous 
line.]

[For consistency with other packages, I've moved the …inputs below 
the arguments field.]

Is this not useful?  If not, could you provide a short comment 
explaining why?

> +                   "--with-gnu-ld"

And here?

Why not use --with-aspell=… as you did for Postgres?

[We don't need to include ‘libre’ (or ‘Free’, ‘open-source’, …) in 
descriptions: there's no other software in Guix.  \o/ ]

Why GPL3+?

[I was unable to get this package to build reproducibly, although 
I tried only disabling #:parallel-build?.]

Kind regards,
