I learned that on OSX it is dyld and not ld; however, changing it to
DYLD_LIBRARY_PATH gave another error:
Traceback (most recent call last):
File "./pyqt_example.py", line 4, in <module>
from gnuradio.qtgui import qtgui
File "/opt/local/lib/python2.6/site-packages/gnuradio/qtgui/qtgui.py",

_qtgui = swig_import_helper()
File "/opt/local/lib/python2.6/site-packages/gnuradio/qtgui/qtgui.py",
line 20, in swig_import_helper
_mod = imp.load_module('_qtgui', fp, pathname, description)
ImportError:
dlopen(/opt/local/lib/python2.6/site-packages/gnuradio/qtgui/_qtgui.so, 2):
Library not loaded:

Referenced from:
/System/Library/Frameworks/Accelerate.framework/Versions/A/Frameworks/vecLib.framework/Versions/A/vecLib
Reason: Incompatible library version: vecLib requires version 1.0.0 or
later, but libLAPACK.dylib provides version 0.0.0
I tried to google this and found some forum discussions suggesting that this
is problem with the port package and that using DYLD_LIBRARY_PATH is not
recommended - instead DYLD_FALLBACK_LIBRARY_PATH can be used. Tried that and
got a different error:
Traceback (most recent call last):
