Yes - for a longer answer take a look into our README file:

http://github.com/cschwan/sage-on-gentoo

This will help you unmasking the required ebuilds.

The good news is: On x86 Sage works fine (there are some testcases which fail, 
look at: http://github.com/cschwan/sage-on-gentoo/issues ) and I would claim 
it works even better than the unmodified Sage itself ;) (latex packages are 
automatically installed and paths set for example).

The bad news is that there are two major problems on amd64:

- You may encounter a bug related to gap (if you try starting Sage it may hang 
at certain point because of gap)
- When exiting Sage there is a certain probability to trigger the random 
SIGABRT failure - that means Sage will work fine until you you exit it.

Of course, we are trying to fix these but the first issue is hard to reproduce 
and the second is hard to debug (because its random).

If you encounter problems mail them to this list.
