emerge -fp downloader

Before replacing Gentoo with Ubuntu on my server I want to give it another chance. The problem is, there seems to be a problem with at least one of the system packages (like autoconf or automake). I tried to compile and install ApacheHTTPD and PHP like I've done it on some other servers, but the Makefile doesn't seem to produce a working install label. For example the Apache Makefile never installs the modules and PHP doesn't install the module before chmodding it.

So I've decided to first run emerge -De system && emerge -De world which should reinstall the whole system. Since my server is not online I have to get the sources from somewhere. So I generated with emerge -pfDe system 2> list a list of all the source packages that have to be downloaded an following small script that should fetch them all on a different machine :-)

#!/usr/bin/perl
if (@ARGV == 0){
    print "downloadlist.pl filelist\n";
}
my $file = $ARGV[0];
open(FILE,"< $file") or die("Couldn't open input file");
if (not -f "distfiles"){
    mkdir "distfiles";
}
download: while(<FILE>){
    if (/^$/){
        next;
    }
    else {
        my @candidates = split / /, $_;
        my @filename = split(/\//,@candidates[0]);
        my $filename = $filename[@filename-1];
        foreach $candidate (@candidates){
            `cd distfiles ; wget -c $candidate`;
            if ($? == 0){
                # Move the file to the storage 
                # directory
                #`mv $filename distfiles`;
                next download;
            }
        }
        print "Failed to download $filename\n";

    }
}
close(FILE);

This will download all the files listed in the $list file (and should also try the mirrors if the download fails) and puts them into the $PWD/distfiles folder.
