Another active Homebrew process is already using openblas.

[c0g]

Homebrew/legacy-homebrew#17730
From there (there's more useful info from the homebrew devs)
I get:

Error: Operation already in progress for openblas
Another active Homebrew process is already using openblas.
Please wait for it to finish or terminate it to continue.

But there is no active homebrew process. OSX 10.8.2, Ruby 1.8.7. I have brew rm'd and reinstalled blas, any ideas?

brew doctor only notifies me of a libwfdb which I have installed (I have mv'd it elsewhere, no help).

This is a duplicate issue of #21, I'm moving all discussion over there, please take a look, and if the suggestions there don't solve your problem, re-comment here and I'll reopen this issue.
