checking for bison... bison -o y.tab.c
LifeLines requires GNU Bison to compile src/interp/yacc.y.
===========================================================================
=======================<phase: build >============================
===> Building for lifelines-3.1.1_1
gmake[1]: Entering directory '/wrkdirs/usr/ports/misc/lifelines/work/lifelines-3.1.1'
gmake[1]: Makefile: No such file or directory
The configure script cannot cope with any value for YACC that is
not "bison -y" and just exits with an error (and exit status 0, so
the build continues and fails in the next phase when it cannot find
Makefile) when it is a different value. Set it to "bison -y"
explicitly.
This will fix building as user, but it is not clear why we do not
see this failure when building as root.
