Source: avogadrolibs Followup-For: Bug #948769 avogadrolibs depends on the openbabel plugin libraries and datafiles in /usr/lib/openbabel/ and /usr/share/openbabel, see ll.60,68 in avogadro/qtplugins/openbabel/obprocess.cpp
Strictly speaking these are provided by libopenbabel5, but it is cleaner I think to have avogadrolibs depend on libopenbabel-dev, which depends on libopenbabel5 (or on its successors, when openbabel updates its ABI).
