I will try a fix shortly, testing take a while on this little computer but it

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




Traceback (most recent call last):

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.
