Component:  ports    |    Version:  2.3.4
 Keywords:           |       Port:  py27-tables
---------------------+--------------------------------
 I first tried to create an hdf5 table using pandas.  But, that failed.
 So, I went to pytables instead, and that also fails with a similar error.
 I'm using py27-tables @3.2.2_2 which is using hdf5 @1.10.0_1
 Here is a simple example, grabbed from the pytables web page

 {{{
 >>> import tables
 >>> from tables import *
 >>> h5file = open_file("tutorial1.h5", mode = "w", title = "Test file")
 >>> group = h5file.create_group("/", 'detector', 'Detector information')
 >>> class Particle(IsDescription):
 ...     name      = StringCol(16)
 ...     idnumber  = Int64Col()      #
 ...     ADCcount  = UInt16Col()     # Unsigned
 ...
 >>> table = h5file.create_table(group, 'readout', Particle, "Readout
 example")
