I think libreoffice, chromium and firefox will be compiled in a chroot from now
on and then emerged as binaries. This is the difference for libreoffice:
Sat Aug 29 06:09:09 2015 >>> app-office/libreoffice-4.4.4.3
merge time: 15 hours, 34 minutes and 2 seconds.
Sun Sep 13 01:36:03 2015 >>> app-office/libreoffice-4.4.5.2
merge time: 15 hours, 13 minutes and 17 seconds.
Sun Nov 29 02:30:04 2015 >>> app-office/libreoffice-5.0.3.2
merge time: 16 hours, 54 minutes and 28 seconds.
Sun Mar 27 09:31:20 2016 >>> app-office/libreoffice-5.0.5.2
merge time: 17 hours and 8 seconds.
Mon Aug 1 22:17:15 2016 >>> app-office/libreoffice-5.1.4.2
merge time: 1 minute and 31 seconds.
(chromium takes even longer!) :-)
