This suggests a bug in the Debian packaging (or an old version?).

But yeah, I can sympathize with all the pain you’ve gone through to
build all this by hand.  That’s a chicken-and-egg problem: the package
manager is here to help you sort this out, but you’re precisely trying
to build it.

Pjotr Prins reported earlier that we don’t have a good bootstrapping
story here, and I come to realize what it means.  ;-)

The lesson here, I guess, is that it would be beneficial to make Guix’s
modularity more apparent, as I did in
<https://debbugs.gnu.org/cgi/bugreport.cgi?bug=27284#121>, so that one
can build Guix piecemeal, without having to install all the dependencies
upfront.

I’m pretty sure we solved it recently but I forgot how.  Do you have the
problem on current master?

Thanks,
