bootstrap difficulties

[Eric Blake]

I'm unable to bootstrap coreutils today, with the following symptoms:

./bootstrap: /home/eblake/gnulib/gnulib-tool  --import --no-changelog --aux-
dir ._bootmp/build-aux --doc-base ._bootmp/doc --lib libcoreutils --m4-
base ._bootmp/m4/ --source-base ._bootmp/lib/ --tests-base ._bootmp/tests --
local-dir gl --import ...
gnulib-tool: module rand-isaac doesn't exist
...
Copying file ._bootmp/lib/alloca.c
Copying file ._bootmp/lib/alloca.in.h
...
You may need to add #include directives for the following .h files.
...
  #include <wchar.h>
  GPL
  License
  selinux-at.h
  #include "acl.h"
...
Don't forget to
  - add "._bootmp/lib/Makefile" to AC_CONFIG_FILES in ./configure.ac,
  - mention "lib" in SUBDIRS in ._bootmp/Makefile.am,
  - mention "-I ._bootmp/m4" in ACLOCAL_AMFLAGS in Makefile.am,
  - invoke gl_EARLY in ./configure.ac, right after AC_PROG_CC,
  - invoke gl_INIT in ./configure.ac.
./bootstrap: cp ._bootmp/lib/alloca.c lib/alloca.c # with edits
mv: cannot move `lib/alloca.c-t' to `lib/alloca.c': No such file or directory

Any ideas what I should try next?
