cross compiling usually means your host and target arches are not the
same. I'm guessing this is not the case so chances are your not really
cross compiling.

If you are really cross compiling then the following packages in a base
system are going to give you problems as they are not really cross aware
_yet_

app-shells/bash-3.0-r4
app-shells/sash-3.7
dev-lang/perl-5.8.4-r1
dev-lang/python-2.3.4
net-misc/iputils-021109-r3
net-misc/rsync-2.6.0-r2
sys-apps/coreutils-5.2.1-r1
sys-apps/file-4.10
sys-apps/kbd-1.12-r2
sys-apps/less-382-r2
sys-apps/procps-3.2.2-r1
sys-apps/psmisc-21.4
sys-apps/shadow-4.0.4.1-r3
sys-apps/texinfo-4.7-r1
sys-devel/libtool-1.5.2-r5
sys-fs/e2fsprogs-1.35
sys-libs/cracklib-2.7-r9
sys-libs/ncurses-5.4-r3
sys-apps/module-init-tools-3.0-r2
net-misc/openssh-3.8.1_p1-r1

Assuming your both of your systems are x86 based then this is really a
trivial task.

First try to match your USE= as close as you can then emerge -B from
your build host and then just scp the package into your target host
/usr/portage/packages/All/ then emerge -(k|K) on your target host to
install it.
