py-tables crash on Mavericks involving blosc

[r.ryans@…]

The latest update to py-tables has caused an error for me on Mavericks on more than one machine. This seems linked to the added dependency on blosc. When running python and trying to import tables an error occurs:

Reverting to the previous Portfile, which omits blosc, makes everything work again for me, but obviously I don't need blosc!

In the future, please use WikiFormatting, and Cc the port maintainers (port info --maintainers py-tables).

Fixed in r116933. Apparently, the version of blosc was too old.
