I tried from 1.1.0, seems like it fails because guile@2.2 does not have with-exception-handler: Backtrace: 5 (primitive-load "/gnu/store/jdf2z2vl4gc6yzl5gglixd5jpflcgikm-compute-guix-derivation") In ice-9/eval.scm: 155:9 4 (_ #(#(#(#(#(#(#(#(#(#(#(#(#(#(#(#(# ?) ?) ?) ?) ?) ?) ?) ?) ?) ?) ?) ?) ?) ?) ?) ?)) 159:9 3 (_ #(#(#(#(#(#(#(#(#(#(#(#(#(#(#(#(# ?) ?) ?) ?) ?) ?) ?) ?) ?) ?) ?) ?) ?) ?) ?) ?))

Please report the COMPLETE output above by email to . I guess the simplest solution is to only do 'with-error-handler' wrapping when guile-version>=3.0 ... Greetings, Maxime.
