If you do not find anything, please try the following:

    USE=debug emerge -1 sage-baselayout

Also, make sure that the GNU Debugger is installed (emerge gdb). You may now 
start Sage with

   sage -gdb

which spawns Sage in a gdb session. Sage will crash just as before, but you 
may retrieve a backtrace via typing

    bt

That output would be interesting and may directly lead us to the root of the 
problem.
