On Guix 1.1, bison 3.5.91 fails to build: CCLD src/bison GEN ../doc/bison.help bison: error while loading shared libraries: libtextstyle.so.0: cannot open shared object file: No such file or directory make: *** [Makefile:9899: ../doc/bison.help] Error 127
As the cause, I've identified a Guix bug: https://lists.gnu.org/archive/html/bug-guix/2020-05/msg00036.html Bruno
