Juergen, 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: sage -t -force_lib "devel/sage/doc/fr/tutorial/tour_advanced.rst" // ** Could not open dynamic library: /usr/lib/singular/p_Procs_FieldQ.so // ** Error message from system: /usr/lib/singular/p_Procs_FieldQ.so: undefined symbol: _Z17nlShort3_noinlineP7snumber // ** Singular will work properly, but much slower. // ** See the INSTALL section in the Singular manual for details. 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 Tools/list-compare-deps sci-mathematics/sage 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. Steve
