'make check' fails on OS X 10.5 with gnuradio 3.1 release

Hello…

After installing all necessary libraries using MacPorts and following
instructions from Jon Jacky
(GNU Radio on Mac OS X), the make check
fails on my MacBook Pro… Ignoring that and issuing ‘make install’
leads to the same error when trying to import gnuradio in python:

dyld: Library not loaded: /opt/local/lib/libfftw3f.3.dylib
Referenced from:
/Users/Jakub/sources/gnuradio/gnuradio-core/src/tests/.libs/test_all
Reason: Incompatible library version: test_all requires version
6.0.0 or later, but libfftw3f.3.dylib provides version 5.0.0
/bin/sh: line 1: 26477 Trace/BPT trap ${dir}$tst
FAIL: test_all

I installed the fftw-3-single using MacPorts, ‘port installed’
includes the following lines:
fftw-3 @3.2_1 (active)
fftw-3-single @3.2_0 (active)

What does the ‘version 6.0.0’ or ‘5.0.0’ refer to? As far as I know
there is no newer version of the fftw-3-single which provides the
library in question. Anyone else came across the same problem?

Any help greatly appreciated!
