From time to time I see questions how to outwit Apple's GateKeeper to get LibreOffice installed. I think a link to <http://www.italovignoli.org/2012/08/libreoffice-and-mountain-lion-macos-x-10-8/> would help a lot until we have our own instruction, it should be added quickly.
Confirmed, and agree: this should be added quickly. Another workaround, which may be _even_ _easier_ for most users, is given here: https://bugs.freedesktop.org/show_bug.cgi?id=53320#c6 IMHO this easier workaround could be added *before* the link to Italo’s (rather complicated) description.
I added the link to Italo's article and a paragraph about the easier solution. My changed page has been submitted for publication.
There is now a paragraph about the problem on the page http://www.libreoffice.org/get-help/installation/mac/ -- thank you very much! Therefore I set this bug report to RESOLVED/FIXED.
