Awesome, thanks for this patch!

I noticed in the README.md that upstream suggests use of GNU Make unless
building from a Git checkout. Did you try that?

The README also suggests that this is only necessary for building from
Git, although it's worth finding out what they mean by "re-generating
certain source files from templates". We prefer to re-build "generated"
source files since they are not really "source files" in many cases.

I think these uses of (system*) could be replaced by (copy-recursively)
and (install-file), respectively.
