[Nix-dev] Checksum error then everything builds from source

[Richard Wallace]

Strange, today I retried from scratch and I no longer see any checksum
errors.  Instead, it just goes straight to building everything from source.

I'm completley stuck at this point, my poor little laptop hasn't got the
oomph to build GHC.  I'd really appreciate some help on this one.

Thanks,
Rich
