Hi, I am facing the following problem. When I try to execute a fortran program through "system" command, I get:
_dyld: lazy symbol binding failed: Symbol not found: __gfortran_transfer_integer_write Referenced from: < path of my executable program> Expected in: /Applications/MATLAB_R2011a.app/sys/os/maci64/libgfortran.3.dylib
dyld: Symbol not found: __gfortran_transfer_integer_write
Referenced from:
<path of my executable program>
Expected in:
/Applications/MATLAB_R2011a.app/sys/os/maci64/libgfortran.3.dylib_
I solved this by running setenv('DYLD_LIBRARY_PATH', '/usr/local/bin') , or setenv('DYLD_LIBRARY_PATH', '/opt/local/lib').
Unfortunately I need at the same time to run code in parallel configuration but now matlab cannot find the /Applications/MATLAB_R2011a.app/bin/maci64 or the /Applications/MATLAB_R2011a.app/sys/os/maci64:
I have already tried to run setenv('DYLD_LIBRARY_PATH', [getenv('DYLD_LIBRARY_PATH') '/usr/local/bin:/opt/local/lib:']) but this reproduces the initial problem (_dyld: lazy symbol binding failed: Symbol not found: [...])
MATLAB Version 7.12.0.635 (R2011a)
Operating System: Mac OS X Version: 10.6.8 Build: 10K549
Thank you in advance for any answers

I had the same problem and at least running my Fortran code declaring the DYLD_LIBRARY_PATH as setenv('DYLD_LIBRARY_PATH', '/opt/local/lib'), in my case as export DYLD_LIBRARY_PATH=/opt/local/lib because I work with bash shell. This solved my problem.

It is probable that you are dynamically loading the wrong version of the gfortran library. On Mac, by default the gfortran dynamic library is loaded in
/Applications/MATLAB_R2013a.app/sys/os/maci64
You can edit matlabroot/bin/.matlab7rc.sh and add the correct path to your dynamic library. I have gfortran with fink, so I have the following line in my .matlab7rc.sh
LDPATH_PREFIX='/sw/lib/gcc4.8/lib'
Upon loading Matlab, I then get
>> getenv('DYLD_LIBRARY_PATH')
ans =
/sw/lib/gcc4.8/lib:/Applications/MATLAB_R2013a.app/sys/os/maci64:/Applications/MATLAB_R2013a.app/bin/maci64/../../Contents/MacOS:/Applications/MATLAB_R2013a.app/bin/maci64:/Applications/MATLAB_R2013a.app/extern/lib/maci64:/Applications/MATLAB_R2013a.app/runtime/maci64
This way, you can load you own Mex/Fortran routines and still use the other Matlab dynamic libraries.

In a multi-user setup, or to preserve changes across MATLAB versions, you may want to copy matlabroot/bin/.matlab7rc.sh to your home directory.

This is probably not the Mathworks-recommended way of doing things, but my solution to system path issues was to add
source ~/.bash_profile
to the first line of the Matlab shell script (i.e. [matlabroot]/bin/matlab), and then within my startup.m file add
setenv('DYLD_LIBRARY_PATH', '');
setenv('DYLD_FRAMEWORK_PATH', '');
I find that this seems to keep all my system paths and other environmental variables in the Matlab and terminal environments in sync with a minimal amount of fiddling on my part. So far, I haven't noticed any issues calling system commands in parallel.

I am probably five years late, but you just set the environment variable in the wrong order. Your desired path should come BEFORE the old one and not after. Of course you were getting the same error: MATLAB was locating the wrong file first and not the one you wanted it to.
