I don't think an LGPL wrapper changes anything. It may now be "legal" to link 
to the wrapper, but it still isn't legal for the application to link to the 
library via the wrapper. The manner in which an author presents his library 
is a strong indication of the author's intention for that library. The 
intention does not change just because a third person has written a wrapper 
for it.
