[gentoo-user] boost-1.62.0-r1 blocked by nothing ??

[Jörg Schaible]

Hi,

now I have an emerge mystery myself: It claims boost is blocked by  ... 
nothing. See yourself:
- emerge tells me that boost is for whatever reason blocked
- I cannot find any entry for this in /etc/portage/**
- eix does not show any kind of mask for 1.62.0-r1
- none of the installed packages show a condition preventing an update

Any idea?

Cheers,
Jörg
