[gentoo-science] [sage-on-gentoo]some strange problem with sympy

["François Bissey" <f.r.bissey@massey.ac.nz>]

Hi all,

I was looking at splitting mpmath from sympy (with the help of the patches 
from fedora) when I came across this at test time:
ebuild sympy-0.6.6.ebuild install
>>> Existing ${T}/environment for 'sympy-0.6.6' will be sourced. Run
>>> 'clean' to start with a fresh environment.
 * sympy-0.6.6.tar.gz RMD160 SHA1 SHA256 size ;-) ...                                                                        
[ ok ]
 * checking ebuild checksums ;-) ...                                                                                         
[ ok ]

I get the same thing with sympy-0.6.7 from portage. I guess it only happens 
when sage is already present so it would not be visible from a clean install
of sage. That sage being installed seem to have an influence on sympy further
merging is worrying. Some more packages could be affected (I tested mpmath
and there is no problem there).

Anyone else sees this?

This is with portage-2.2-rc97 that may have an influence.

Any idea for debuging this problem should it be real? ebuild --debug wasn't 
helpful, I would need to run "python2.6 setup.py build -b build-2.6" with some 
debug output.

Cheers,
Francois
