Documentation build of pptable failed silently

[bgamari]

Here we see that the documentation build for the upload of the initial version of the pptable package failed, yet the build remains in "Docs pending" state. This is quite odd as the build did not fail due to a missing target like in #543. Instead, the issue is just a run-of-the-mill build error,

Usually hackage-server notices when a package fails to build like this. It's totally unclear why it didn't in this particular case.

Simlar for https://hackage.haskell.org/package/haquery-0.1.1.3/, still "pending".

@bgamari we've changed the builder since this issue, and we don't seem to have had a repeat? do you think its worth leaving open?

I'd say close it; it can always be reopened if it occurs again.
