[gentoo-science] sage-4.3.5-r1 && sage-core

[Steven Trogdon]

Christopher,

The follow probably only applies to amd64. Sage will not install with the  
subject ebuilds. The
"sage -c" during postinstall fails because the files

	/opt/sage/local/lib/sage-flag.txt
	/opt/sage/local/lib/sage-current-location.txt

cannot be written since /opt/sage/local/lib doesn't exit. I suppose the files  
are needed. One can create the symlink lib -> lib64 if lib is needed or  
whatever. Even if this is fixed "sage -c" fails because the amd64-hack patch  
does't take. The spkg-install is bypassed with the sage-core ebuild. I tried a  
variety of things to get Sage to install and adding

	append-flags -fno-strict-aliasing

to the sage-core ebuild works here. I'm not sure of the impact on ~x86 or ~pcc.
