i had a problem with the same package and i just did emerge libtool and then emerge xorg-x11 again and it seems to have worked fine.

its ok, i found out the problem was i didnt bring dhcpcd during boot up!! but ofcourse when i put in the livecd it did it for me so i could download the libpng package...aaahhh dear me! feel so brainless!

ok, it seems to be happening with everything i try to emerge.

thought i might have fixed the problem by downloading the libpng-1.2.8.tar.bz2 myself and put it in the distfiles folder in portage but that did work until it came to the next package which was:

opengl-update-2.0_pre4-r1

and that came up with the same problem of Temporary failure in name ...

when i enter:

ACCEPT_KEYWORDS="~x86" emerge xorg-x11

gentoo cant seem to download the libpng-1.2.8.tar.bz2
it tries a few places before giving up

Temporary failure in name resoloution
!!! Couldn't download libpng-1.2.8.tar.bz. Aborting

is there any way of fixing this so i can emerge xorg??

the same thing happens even with -mozilla
i had a good look at the output and it also says HAL library missing, Xinerama present but cannot be compiled, and not building roku HD1000 compatible video output
and then right at the end
!!! ERROR: media-video/vlc-0.8.1 failed.
!!! Function src_compile ...

i still cant get vlc 0.8.1 to compile even with:

ln -s /usr/lib/MozillaFirefox/xpidl /usr/bin/xpidl
& also tried:
ln -s /usr/lib/xpidl /usr/bin/xpidl

it still says failed because it cant fix xpidl path
any ideas what i can do???

thank you so much, this had me stumped for ages and there was no reply in the chat rooms either!! ahh thank you thank you!!!
