[gentoo-user] howto recover gcc from another system

[James <wireless@tampabay.rr.com>]

Hello,

Well running a routine --depclean somehow
I lost the only copy of gcc on the system....

CFLAGS="-march=k8 -msse3 -O2 -pipe"
CHOST="x86_64-pc-linux-gnu"
CXXFLAGS="${CFLAGS}"

I have a a similar system set like this:

CFLAGS="-march=k8 -O2 -pipe"
CHOST="x86_64-pc-linux-gnu"
CXXFLAGS="${CFLAGS}"


Since there is no gcc-bin to emerge (ha ha)
I guess I'll have to copy over the binary of
 orsys-devel/gcc-4.4.4-r2 from another system. 
GUIDANCE on that is most welcome.

Additionally, this could be prevented by keeping
the latest current stable gcc as well as the 
previous current stable gcc on the system,
perhaps via the world file? Or Another method
to ensure at least 2 versions of gcc are
always on a given system?

It's a first time deleting the compiler,
still do not know how it happened, as I
did look over the -p --depclean first....
