[gentoo-user] masked packages

[n952162]

Hello.

I'd like to emerge *radicale*, but see it's masked for amd, etc.  I
looked at the portage meta data and the ebuild to see if I could find
out why it should be masked - it's just a python program, supposedly. 
But I can't find out anything.  This warnings are unequivocal about
unmasking a package if you don't know why it's masked
(https://wiki.gentoo.org/wiki/Knowledge_Base:Unmasking_a_package). Does
anybody have any ideas?
