Hi Stephen,

This is correct.

I don’t understand this.  At what point does it use that Guile?  When
building a package that has “guile” as one of the inputs it is *that*
variant of Guile that is used.  Within the build environment Guix
doesn’t use any profiles.

As long as the configure script provides an option to override the
location Guix will be happy.
