[gentoo-science] Interval arithmetics with Python

[gentoo-science] Interval arithmetics with Python

[Jan Marten Simons]

Hi,

I'm interested in doing interval arithmetics with python. I stumbled 
upon PyDx which can use mpfi for this. (mpfi itself uses mpfr, which is 
in portage). Additionally PyDx is using GMPy, which is also in portage.

So has anyone here bothered to write ebuilds for mpfi and PyDx, yet?

With regards,
Jan

I did an ebuild for mpfi by now ( http://phpfi.com/298847 ), but I need 
some help with the ebuild for PyDX ( http://phpfi.com/298845 ):

During install I get "access denied" errors and I don't know how I can 
tell setup.py to install into the sandboxed directory (image).

With regards,
Jan

I've got the ebuilds for dev-libs/mpfi and dev-python/PyDX working now. 
It would be nice if those could be added to the overlay.

I found some discussion about an ebuild for cctbx in the archives. Is 
there any news to this? I'm interested in this package as well.

With regards,
Jan

Not really any news, although I'm also interested in it. More generally, 
there's a new contributor who has recently posted ebuilds for a number 
of crystallography packages on bugzilla. The 2xxxxx bugs in this list 
(created by pybugz) are all his:

I'm doing some cctbx development, so I might end up trying to make an 
ebuild for it. It uses scons and has pretty complex settings, which 
makes it more painful.

Thanks,
Donnie
