That blocker means that you should remove sage-4.5.1 (its blocking 4.5.1, not 
4.5.2!) first and then perform the upgrade - thats because I have put the 
.desktop file from sage into sage-baselayout. Without this blocker there would 
be file collisions.

The symbol dgetri_ is from lapack which should be removed from linbox; merge 
linbox again (make sure its -r3) and try to start Sage. Please report back if 
it works or not!
