Unable to build derivation, even if inputs are available

[Christopher Baines]

Hey,

I thought I was beginning to understand derivations, but I've hit a
problem I can't explain.

I've got a derivation in my local store, and as far as I can work out,
all the outputs for all the required inputs of this derivation are in
the store as well.

  scheme@(guix-user)> (use-modules (srfi srfi-1) (guix derivations))
  scheme@(guix-user)> (define drv (read-derivation-from-file 
"/gnu/store/mafs37vw7k65ah071p8f080c9y1y3l7n-bbmap-35.82.drv"))
  scheme@(guix-user)> (define required-outputs (append-map 
derivation-input-output-paths (derivation-inputs drv)))
  scheme@(guix-user)> (define missing-outputs (remove file-exists? 
required-outputs))
  scheme@(guix-user)> missing-outputs
  $1 = ()

Despite that, I can't build it. If I try, Guix says I'll need to build
~80 [1] other things along with the derivation I actually want to build.

Any ideas?

Thanks,

Chris
