Hey, Sorry to distract you ;-) but while I was at it I couldn’t help but have it build Guile with several ‘configure’ options:
http://hydra.nixos.org/jobset/gnu/guile-master/all Here you see builds ‘--without-threads’, ‘--disable-deprecated’, etc. The good news is that some of them actually compile. ;-) Others should be easily fixed. For the curious, all this is done programatically: https://svn.nixos.org/repos/nix/hydra-config/gnu/trunk/guile/release.nix Cheers, Ludo’.
