[gentoo-user] world update problem again

[John Covici]

Hi.  So, on my latest attempt at a world update today, I am getting a
crazy problem with libpng, with some packages insisting on the use
flag -apng (portage made me put it in), but other packages insisting
on the use flag apng.

Here is the actual portage output:

Total: 232 packages (198 upgrades, 2 downgrades, 2 new, 6 in new
slots, 24 reinstalls, 2 uninstalls), Size of downloads: 3,451,440
