 reveals that fftw-3-3.3.4_0 built on Yosemite is linking its shared
 libraries with "-flat_namespace" as seen from the missing TWOLEVEL flag
 expected from "-undefined dynamic_lookup".

Comment:

 The [[comment:35:ticket:44596|Libtool MACOSX_DEPLOYMENT_TARGET bug]]
 again. The [[attachment:fftw-3.patch|attached change]] should fix it,
 although the issue still needs to be reported upstream. The problem was
 fixed in [http://lists.gnu.org/archive/html/libtool/2014-10/msg00010.html
 the latest Libtool release], so they shouldn’t have to do anything more
 than update their Libtool and regenerate everything.

 Sean, may I commit this, or do you want to handle it yourself?
