Well, spamassassin flags the messages because they have the date in the 
future.  I've got a rule allowing messages from the list so it goes through, 
but some sites might block your email whether you know it or not.

As far as compiling goes, it wouldn't matter either.  I'd worry about the 
rsync process as, since you are in the future, the timestamps from your local 
system and the remote rsync mirror might indicate to your system that you're 
newer than what the mirror thinks.

Enough preaching, I was just pointing it out in case you weren't aware.

Well if you're not running X you can slim down quite a bit.  The list you 
included has all multimedia and stuff for more of a desktop system.  My 
server box has a much shorter list:

USE="-mbox -gnome -kde -X atm maildir cdr bzlib curl -emacs exif fam ftp 
gnutls -ipv6 kerberos libwww mime mmap mmx mng nptl pcre pic php perl sockets 
sse ssl sysvipc posix sasl shared sharedmem usb mysql xml cups pam imap aac 
apache2 bash-completion berkdb bidi bzip2 canna caps cjk clamav cpdflib crypt 
dbus dbx dio ethereal examples expat flac freewnn gd gdm javascript ncurses 
nls png jpeg junit ldap libclamav mcve ming openntpd mysqli nas netboot 
openal tcpd spl spell snmp sockets soap python samba vhosts xml2 zlib"

It will show all of the dependencies as well as the package.  For example, you 
had gnomedb in your USE list, but -gnome also.  If you emerged a package that 
used the gnomedb flag, but gnomedb has dependencies upon gnome, you're either 
going to be looking at a  nasty message about a blocked package, the package 
won't install, or you'll get gnome anyway (note this is just an example, I 
don't know for sure what the gnomedb flag would incur).

I did include them in my USE flags.  I don't have any clue what, if any, 
effect they have on the system.  Many of the USE flags have descriptions 
available, but I haven't seen any sort of cross-reference that says when USE 
flag X is set, Y happens as a result.

I look at these as clarifying the base system architecture, but do not have 
the same kind of impact as gnome/-gnome would have.
