Making Arch packages out off Gentoo Binary packages

Question

emerge in portage can build binary packages of what it compiles.
emerge -b konqueror konq-plugins nsplugins
and we get splik KDE pkg of konqueror with all it dependencies
arch pkg vs gentoo pkg
gentoo pkg doesn't have 2 files: .FILELIST and .PKGINFO + it makes tar.bz2 not tar.gz packages
how to convert a gentoo package
- unpack
- add .FILELIST (list all files >> .FILELIST)
- create .PKGINFO data from package Ebuild can be used
- tar.gz it and done
Someone good in bash/sh scripts could write something so it would convert those packages more automaticly. To make gentoo packages you need gentoo but you don't have to install it like a normal distro:
1. get i686 stage from here 85MB
- untar it to /home/user/gentoo
tar -xvjpf file.tar.bz2
- cp /etc/resolv.conf to gentoo/etc/
- modify /etc/make.conf (in gentoo)  add:
ACCEPT_KEYWORDS="~x86"
- add USE flags
and you can set CFLAGS and CXXFLAGS... jackass (unofficial stages) uses someting like:
CFLAGS="-march=i686"
CFLAGS="${CFLAGS} -pipe"
CFLAGS="${CFLAGS} -O2"
CFLAGS="${CFLAGS} -fweb"
CFLAGS="${CFLAGS} -frename-registers"
CFLAGS="${CFLAGS} -fforce-addr"
CFLAGS="${CFLAGS} -momit-leaf-frame-pointer"
CFLAGS="${CFLAGS} -fomit-frame-pointer"
CXXFLAGS="${CFLAGS} -fvisibility-inlines-hidden"
as root in console chroot to gentoo:
- go to folder with gentoo
chroot ./ bin/bash
env-update
source /etc/profile
then if net works:
emerge sync
after updating portage tree you can emerge packages

Separate KDE packages are bit hard to make via pkgbuild because you have to:
- make spited source packages
- set dependencies for them
And it isn't easy Gentoo has splitted KDE sources, but ebuilds aren't to friendly for pkgbuilds But running gentoo binaries on arch will help find all required dependencies for those splitted source packages and based on that – make pkgbuilds
Currently I'm using Gentoo with splitted KDE packages and they do work faster – less dependencies etc. + they are easy to update (1MB K*something instead whole kdebase*or*something). My vacations starts next week and I'll try to make some gentoo -> arch work in the next months ;]
(and I switched to Gentoo to get all the soft I wanted "on-demand" – I have only modem at home and now I have some exams so I can't play with arch to get them.)
