Hm. I think I had that with nyacc too. This worked for me:

  GUILE_PKG([3.0])
  GUILE_PROGS([2.9.5])

I think this is due to our currently apocalyptic [1] situation:

  tomas@trotzki:~/src/guile/nyacc$ guile
  GNU Guile 2.9.5
  [...]
  
  Enter `,help' for help.
  scheme@(guile-user)> (version)
  $1 = "2.9.5"
  scheme@(guile-user)> (effective-version)
  $2 = "3.0"

(replace 2.9.5 for 2.9.8 as appropriate).

Cheers
[1] Although apocalyptic has often a negative connotation, I'm using
   it here in its more original sense [2], i.e. full of gleeful
   expectation :-)
