You mentioned lsof but there is a utility in base which you probably
don't know about called fstat(1), which does a lot of what lsof does.

IIRC, the sources for 7.2 should be on the CD (run sysinstall(8) after

Then update the sources with csup(1) using the correct tag: RELENG_7_2

There's a supfile, /usr/share/examples/cvsup/standard-supfile, which
you can change the default host and cvs tag of and it should work.
