The following interaction (in OS X) summarizes the situation:
% echo $DYLD_LIBRARY_PATH
/Applications/MATLAB_R2010a.app/bin/maci64
% grep -r _engClose $DYLD_LIBRARY_PATH
Binary file /Applications/MATLAB_R2010a.app/bin/maci64/libeng.dylib matches
% export DYLD_LIBRARY_PATH
% python

Traceback (most recent call last):

ImportError:
dlopen(/opt/local/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/mlabrawmodule.so,
2): Symbol not found: _engClose
Referenced from:

In summary,
1) dlopen produces a "Symbol not found: _engClose" error;
2) according to grep, a file accessible through the variable
DYLD_LIBRARY_PATH matches the string "_engClose";
The permissions of the file in question are all OK (0555); likewise,
the permissions of all the prefix subpaths leading to this file
are fine.
(For all I know, it is possible that, even though the libeng.dylib
file matches "_engClose", this is only a fragment of a longer symbol
name.)
Can anyone suggest a way to fix this error?
Thanks!
