>Description:

My machine has been sitting for hours after this output:

===> Installing dependencies for libsndfile-1.0.29nb2
[..]
=> Tool dependency autogen-[0-9]*: NOT found
[..]
===> Building for guile22-2.2.7nb3
[..]
Making all in bootstrap
gmake[2]: Entering directory '/usr/pkgobj/lang/guile22/work/guile-2.2.7/bootstrap'
  BOOTSTRAP GUILEC ice-9/psyntax-pp.go

I have been told there are chances it is not just looping but will complete
after a few more hours.

This is just plain stupid and should be avoided. Can we get rid of autgen?
