can't launch buffer

[dinojr]

Since a recent upgrade of emacs (from a 24.xx to 24.2.50.1) wg-help fails with:
wg-help: Symbol's function definition is void: temp-output-buffer-show. What's going wrong ?

[qdot]

When's your build date? I'm on 24.2.50.1, and M-x wg-help seems to work.

I'm seeing a few reports of this (missing temp-output-buffer-show) on the emacs-devel list too, looks like if you're building yourself you may need to completely clobber and rebuild or something?
