I think in consultation with Tim (many thanks!) I've figured out why
things aren't working, and how I can lightly hack around the problem.
The first issue seems to be that I'm trying to compile modules from
the base library source against preinstalled versions, not versions
I've built myself - meaning I lack .hi-boot files. The second issue
seems to concern various flags and meanings of flags.

What I'm doing is clearly well beyond anything that was ever
contemplated, but is working near enough that I can use it to do the
next stages. Once I have everything a bit more stabalised, I'll post
up my code and my intentions and try and classify the exact issues I
am running into.

Thanks
