That is what I thought. I tried to add a
  #:use-module ((guix build-system gnu)
                #:select (gnu-build-system))
but that was not enough.

That also does not seem to work. I split out the packages into two modules,
python for the python binaries that use gnu-build-system, and python-modules
for the packages using python-build-system.

The same error occurs, (alist-replace %standard-build-system) ends up with
the configure from gnu-build-system. 

Could it have something to do with the way %standard-phases of python are
derived from those of gnu? Or that code is quoted and executed in a different
environment from where it is written?

Maybe we should try to use a variable name %python-standard-phases instead.
