The relevant error is:

This should be fixed in HEAD by #58

In general I would suggest using HEAD along with development versions of libraries or compilers, though if this is causing substantial inconvenience I can try to put a release out.

I've patched the build to succeed in NixOS, so there's no immediate problem for us.

I've uploaded 4000.2.14 to roll up a few minor outstanding fixes including this one.
