[Maria-developers] Building LibraOffice w/ MariaDB installed fails apt-get build-dep

Hi, I'm having trouble with MariaDB as is described here: https://ask.libreoffice.org/en/question/96902/building-lo-w-mariadb-installe... I suspect that there might be an issue with the virtual package or something like that. Any idea of what is going wrong or how to fix it? Thanks -- howard
