The LGPL 2.0 had an example describing the problem: If your program is
statically linked and uses a proprietary library that has a licence that
does not permit the redistribution of the files required to rebuild your
software, then you cannot use the LGPL library. 

As for FFTW, if one wants to distribute an proprietary ITK based program
that uses FFTW, one can buy a non-GPL licence from MIT that allows
redistribution without source code.

Well, ideal" is probably not the word I would choose for the aims of
abstinence-only sex-education - but then again I'm from Germany, live in
Spain, and I prefer to publish my software under the GPL - I just don't
want to imagine that someone sells me back my own software with my very
own bugs, and I can't even fix them ;)

Best,
