Libreoffice has apparently bumped their libmysqlcppconn version check from 5 to 6. mysql-connector-c++-1.1.1 provides libmysqlcppcon-[1.0.]6 while current stable 1,1.0-r1 only provides 5 (nvm the (upstream?) numbering blooper there), so the real dependency would be nice to be put in place. Result with 1.1.0-r1: (snip) checking for main in -lmysqlcppconn... yes checking version... configure: error: not suitable, we need >= 1.0.6 (/snip) Result with 1.1.1: (snip) checking for main in -lmysqlcppconn... yes checking version... OK (/snip) Naturally this only affects those of us running a mixture of stable and testing graded packages, but might go unnoticed when stabilizing libreoffice later on.
Box had other dynamic library issues. After fixing them this was no longer an issue. Sorry for the noise.
