But I forgot that, and ended up with both /lib/libreadline.so.8 AND /usr/local/lib/libreadline.so.8 on my machine, leading to woe when compiling the latest lang/python36. Unfortunately, the base version readline was quite a bit older than the one from ports.
Nevertheless, the ports version is explicitly linked as libreadline.so.8, the same as the old base version, so python36 tried linking to the base version and failed because it did not contain the new(ish) function rl_callback_sigcleanup. There's no question I shot myself in the foot by not deleting the old libraries (an omission I have now remedied after a fair amount of thrashing around to see what was wrong), but it might have made my life a little easier if the port devel/readline linked itself as libreadline.so.9 instead of 8. Is there a recommended practice (or should there be one) to change the .so version when simultaneously moving a base library to ports and a new version? -- George
