lang/spidermonkey fails to build unless devel/readline is installed. devel/readline is not specified as something spidermonkey60 does depend on, and readline is part of the system with FreeBSD 12 anyway. System: FreeBSD lightning 12.1-STABLE FreeBSD 12.1-STABLE r357702 LIGHTNING amd64 (without devel/readline installed) Error: ... > checking for readline in -lreadline... no > configure: error: No system readline library found. With devel/readline installed, spidermonkey60 builds and installs as normal.
Over to maintainer.
This is for an old version of spidermonkey which is python27 only, please use a modern version. *** This bug has been marked as a duplicate of bug 244237 ***
