Possibly.  If you use ./configure -C, the ‘config.cache’ file also gets
stale after GC.  But even if you don’t, (guix config) might be referring
to things that have been collected, so you have to:

  rm -f config.cache && ./configure

I’m closing this bug, but do reopen it if you think something’s really
broken.  :-)

Thanks!
