It threw errors about kernel sources missing. So, I looked and sure enough this box doesn't have them. The documentation I have says to install them via sysinstall. That failed both automatically and manually configured server references.
I then found elsewhere that sysinstall is no longer supported and that sources should be pulled with Subversion. I pulled the sources into /usr/src with subversion. Lsof still pukes on compile. The Makefile dependency that it is missing appears to be
/usr/src/sys/kern/kern_lockf.c. I've got a
/usr/src/sys/kern with several files, but no
kern_lockf.c anywhere to be found.
Supposedly I have the current sources and the current ports. What's going on?
