The install of Sage still fails. The sage-singular install leaves an  
odd symlink for LIB under
/opt/sage/local. LIB points to the portage work directory. Here this is  
usually

LIB -> lib
lib -> lib64

However, this is not the issue. If I fix the symlinks the install of  
sage still fails. I get

cd /var/tmp/portage/sci-mathematics/sage-4.3.5/image//opt/bin/; ./sage  
-c
Setting permissions of DOT_SAGE directory so only you can read and  
write it.
