I just pulled and updated (f533820e7248) before carrying out any further tests. Now I get the same error as Jenkins:

$ isabelle build -b HOL
*** No such file: "/Users/blanchette/isabelle/src/HOL/Main.thy"
*** The error(s) above occurred for theory "Main" (line 8 of "/Users/blanchette/isabelle/src/HOL/ROOT")
*** The error(s) above occurred in session "HOL" (line 3 of "/Users/blanchette/isabelle/src/HOL/ROOT")
