I installed from source, compiling by myself.

No. Installed HaXml and tried it with this results.

No. Just the HaXml default ones. Nothing weird as far as I can see.

No. Also because that would result in ghc not compiling the code, I
think. Instead, the code *gets* compiled by ghc, *but not* loaded by
ghci: same code, obviously.

No, just version 1.13.1. No failed attempts whatsoever.

I did not mess with anything. I believe my problem is weird, indeed.
The solution you describe is feasible, but I'd like to get the general
