I just updated the portage tree. But there seems to be a dependency conflict
when I try to update the system. This is the first time I encounter this
kind of problem. Could you guys help me out? Thanks in advance^_^

-------------------

$ sudo emerge -avuDN world

These are the packages that would be merged, in order:

Calculating dependencies... done!
[ebuild  NS   ~] sys-kernel/gentoo-sources-2.6.39-r1 [2.6.39] USE="-build
-deblob -symlink" 72 kB
[ebuild     U  ] dev-libs/libdbusmenu-qt-0.8.2 [0.6.2] USE="-debug -doc%

[ebuild     U  ] net-ftp/lftp-4.2.3 [4.1.3] USE="nls ssl -gnutls -socks5"
1,296 kB
[ebuild     U ~] media-sound/pulseaudio-0.9.22-r2 [0.9.22] USE="X alsa
asyncns bluetooth caps dbus glib ipv6 tcpd udev -avahi -doc -gnome -jack
-libsamplerate -lirc (-oss) -realtime
(-system-wide) -test" 0 kB
[ebuild     U ~] sys-fs/udisks-1.0.2-r4 [1.0.2-r1] USE="nls -bash-completion
-debug -doc -remote-access" 0 kB

Total: 6 packages (5 upgrades, 1 in new slot), Size of downloads: 1,997 kB

!!! Multiple package instances within a single package slot have been pulled
!!! into the dependency graph, resulting in a slot conflict:

sys-fs/udev:0

  (sys-fs/udev-171-r1::gentoo, ebuild scheduled for merge) pulled in by
    >=sys-fs/udev-171[hwdb] required by
(media-sound/pulseaudio-0.9.22-r2::gentoo, ebuild scheduled for merge)

  (sys-fs/udev-151-r4::gentoo, installed) pulled in by
    >=sys-fs/udev-147[extras] required by (sys-fs/udisks-1.0.2-r4::gentoo,
ebuild scheduled for merge)
    (and 3 more with the same problem)


It may be possible to solve this problem by using package.mask to
prevent one of those packages from being selected. However, it is also
possible that conflicting dependencies exist such that they are
impossible to satisfy simultaneously.  If such a conflict exists in
the dependencies of two different packages, then those packages can
not be installed simultaneously. You may want to try a larger value of
the --backtrack option, such as --backtrack=30, in order to see if
that will solve this conflict automatically.

For more information, see MASKED PACKAGES section in the emerge man
page or refer to the Gentoo Handbook.

Apparently, though unproven, at 12:38 on Thursday 09 June 2011, Einux did 
opine thusly:

There's no way to fix this right now.

You need udev version 171 or greater with the hwdb USE flag set as required by 
pulseaudio (which is fine, your system will do this OK)

You also need udev version 147 or greater with the extras USE flag set as 
required by udisks. udev-171 does not meet these requirements as it does not 
have the extras USE flag (check the output of -p above, it is not listed).

So portage will look for earlier and earlier versions of udev to find one that 
does support extras, but the first one it finds conflict with what pulseaudio 
needs.

You have some options:

- it's a bug, it needs to be reported. But you will not need to do this as 
every unstable user has it also and there will be 100s of bugs already (udev 
is needed by almost everyone)

- mask/downgrade pulseaudio to a version that can use an earlier udev

- wait a day, resync, try again.

The third option is usually the one that works best.

it gets normal after I re-synced the portage tree.

Thanks for your detailed analysis ^_^
