Re: ITP: pyspeckit -- toolkit for fitting and manipulating spectroscopic data in Python

[Vincent Prat <vinceprat@free.fr>]

Hi,

I have made some progress in packaging pyspeckit.
However, when I try to build it with pbuilder, the build fails during
the tests with the following backtrace:

Traceback (most recent call last):

ImportWarning: can't resolve package from __spec__ or __package__,

Any idea on how to fix that?

Thanks in advance.
