If there is only one ABI version of lensfun installed, this would
work.  If you want to make possible that liblensfunM can be
installed locally parallely to liblensfunN, you need to put the
database format version (not the ABI number) in the -data package.

(Also note that the upcoming major Lensfun release will not be able
to read older database versions.  But this only makes the comparison
expression a little bit longer.)

This is correct.  At least, if people read directly the library
files, they are on their own.

Tschö,
Torsten.
