[yt-users] install error

[Elizabeth Tasker]

Hi,

We've had some problems installing yt via the install script.

Initially it did not download distribute, which we did by hand. Then, it couldn't get pip, so I commented that line out and now it's died on cython with:



cythonc:> yt/utilities/lib/PointsInVolume.c

cythonc:> yt/utilities/lib/QuadTree.c

cythonc:> yt/utilities/lib/VolumeIntegrator.c
building extension "yt.utilities.lib.grid_traversal" sources
cythonc:> yt/utilities/lib/grid_traversal.c

Has anyone had a similar experience?
