I have just compiled the RC1 libreoffice-4.0.1.1 successfully using media-libs/libvisio-0.0.24 app-text/libmspub-0.0.5 Probably ... though I did not test functionality of these modules. Reproducible: Always
I have just compiled the RC2 libreoffice-4.0.1.2 Needed free diskspace can be downgraded to a minimum of 3gigaByte. Maybe 4gB but 6gB are definitly not needed with >libreoffice-4
Please do not report the requests for the RC versions. I always add just the latest one which gets renamed for the release. Wrt the separate packages feel free to open bugs per package as I often forget to bump them on gentoo side and do so only in suse :P Anyway thanks for the report because I indeed forgot about the libmspub.
