modify wl; IMO that should be done upstream, which is why I reported
this as a bug.

Unfortunately it looks like there are many copies of pgg lying around.

It seems like emacs ever-more-desperately needs package dependency
management.  el-get provides that, but only if the packages themselves
don't deliver other packages as though they were sub-parts.
