&gt;<br>
&gt; My last mail was not complete.  I wanted to say &#39;emerge -v1 scipy&#39; fails<br>
&gt; after downgrading numpy, but &#39;USE_PYTHON=&quot;2.7&quot; emerge -v1 scipy&#39; works.<br>
&gt;<br>
&gt; And I reemerged also matplotlib, but as described in an other thread<br>
&gt;<br>
&gt; sage -testall<br>
&gt;<br>
&gt; still generates still between about 150 and 220 errors.<br>
&gt;<br>

Do you by chance have singular-3.1.3.1 or any other singular except the sog singular (singular-3.1.1.4-r1) installed. If so, you should install the sog singular. When I have an incorrect singular installed I get things like:<br>


<br>
sage -t -force_lib &quot;devel/sage/doc/fr/tutorial/tour_advanced.rst&quot;<br>
// ** Could not open dynamic library: /usr/lib/singular/p_Procs_FieldQ.so<br>
// ** Error message from system: /usr/lib/singular/p_Procs_FieldQ.so: undefined symbol: _Z17nlShort3_noinlineP7snumber<br>
// ** Singular will work properly, but much slower.<br>
// ** See the INSTALL section in the Singular manual for details.<br>
<br>
which appear in your sage_test_impala.log file. This will not cure all your problems but perhaps is a start. I suspect, for some reason, you have unstable packages installed that do not play well with sage (my guess). Could you post the output of<br>


<br>
Tools/list-compare-deps sci-mathematics/sage<br>
<br>
Tools is a folder under the sog overlay. I believe the tool still reports things correctly. This may give an indication of what you have installed.<br>
