[Brent H. <hu...@wi...>]

Any suggestions for what might be wrong?

~/tmp/pytables-2.0> python -c 'import tables; tables.test()'

Performing only a light (yet comprehensive) subset of the test suite.
If you want a more complete test, try passing the --heavy flag to this
script
(or set the 'heavy' parameter in case you are using tables.test() call).
The whole suite will take more than 2 minutes to complete on a relatively
modern CPU and around 80 MB of main memory.
