BUG/NotImplemented datashape conversion from void?

[jreback]

In [1]: from datashape import dshape

In [2]: from dynd import ndt

In [3]: dshape(ndt.type('?int64').dshape)
Out[3]: dshape("?int64")

Is this just not implemented?

In [4]: dshape(ndt.type('?void').dshape)

  File <nofile>, line 1
    ?void

It looks to me like your Mac has some issues with being unable to find the C++ standard library. Unfortunately, I don't understand the details at all. It doesn't make sense that libdynd is fine, but dynd-python is not.

Another guess: Do you run setup.py as root? If so, try without it.

hmmm it doesn look like I am picking up something weird.
