Hi,
This is my understanding:
Yes, libsander (LGPL v3) can be linked with libpbsa (GPL v3). But then it
(libsander) will be treated as GLP v3 derived work (since GPL v3 is more
less permissive than LGPL v3). So non-GPL license programs are not allowed
to to link to libsander.
So we either
- make pbsa license as LGPL v3 or more permissive
- or unlink libsander to libpbsa (unlikely)
- make sander/libsander GPL v3 (unlikely since we (e.g: you, ...) want it
as LGPL v3)

LGPL?)
yes, that's it.
PS: May be Jason can chime in here. He's good at explaining things (among
others). :D
