The problem is, as far as I can see, that that read option interferes with srfi-97 names for modules. This is a guile issue, and not one that really has an obvious solution, however there are two options as far as I can see.

1. Go through and change all srfi-97 module names to guile-format srfi names.
2. Find out where the user's init file gets loaded during a build, and make sure it doesn't.

2 seems like the appropriate resolution, since I don't see why we should need access to the user's config file while building.

hmm, after some back and forth with tupi he clarified that init.scm is not .guile, which I thought it was. init.scm is not documented in guile's manual, but it is in guile's NEWS. This file AFAICT always gets read, so it needs to be a solution in guile.
