+Hi!\r
+\r
+The python bindings fail to load libnotmuch with the new version of\r
+MacOS X (10.11). Running "afew", a tagger written in Python gives:\r
+\r
+Traceback (most recent call last):\r
+  File "/usr/local/Cellar/afew/HEAD/libexec/bin/afew", line 9, in <module>\r
+    load_entry_point('afew==0.0.0', 'console_scripts', 'afew')()\r
+  File "build/bdist.macosx-10.9-x86_64/egg/pkg_resources.py", line 356, in load_entry_point\r

+  File "build/bdist.macosx-10.9-x86_64/egg/pkg_resources.py", line 2476, in load_entry_point\r
+    except ValueError:\r
+  File "build/bdist.macosx-10.9-x86_64/egg/pkg_resources.py", line 2190, in load\r
+    parse_map = classmethod(parse_map)\r
+  File "/Library/Python/2.7/site-packages/afew-0.0.0-py2.7.egg/afew/commands.py", line 27, in <module>\r
+    from afew.Database import Database\r
+  File "/Library/Python/2.7/site-packages/afew-0.0.0-py2.7.egg/afew/Database.py", line 23, in <module>\r

+    from .globals import (\r
+  File "/usr/local/lib/python2.7/site-packages/notmuch/globals.py", line 32, in <module>\r
+    raise ImportError("Could not find shared 'notmuch' library.")\r
+ImportError: Could not find shared 'notmuch' library.\r
+\r
+Setting DYLD_FALLBACK_LIBRARY_PATH to /usr/local/lib (where\r
+libnotmuch4.dylib resides) did not help.\r
+\r
+As Eric Wang's response in this thread suggested\r
+http://stackoverflow.com/questions/32905322/oserror-dlopenlibsystem-dylib-6-image-not-found\r
+I've substituted \r
+\r
+nmlib = CDLL("libnotmuch.so.{0:s}".format(SOVERSION))\r
+\r
+in globals.py\r
+\r
+nmlib = CDLL("/usr/local/lib/libnotmuch.{0:s}.dylib".format(SOVERSION))\r
+\r
+This resolved the problem for me.\r
+\r
+With kind regards, Robert Künnemann\r
