Does anyone have any insight on how to resolve this problem?
I'm trying to build a thunk.dylib for use in calling a .dylib in matlab. This method works in windows 7, so its an operating system specific problem. Debugger won't step in to the function loaddefinedlibrary for further investigation. The symbolic link /opt/refprop/librefprop/librefprop.dylib does in fact exist. See below the matlab error output for info from terminal showing the links exists:
fyi thunk.m line 4 is the only command in the file.
Error using loadlibrary (line 422)
There was an error loading the library "/opt/refprop/librefprop.dylib"

It is likely that a function in the libgfortran runtime library is not found in the MATLAB application directory, where it is expected. A possible workaround would be to use a soft (symbolic) link for the libgfortran.3.dylib.
1. If gfortran is installed on your machine, this DYLIB is located at /usr/local/lib/libgfortran.3.dylib
2. Rename the DYLIB file in the MATLAB application directory
3. Create a soft link for the DYLIB: ln -s /usr/local/lib/libgfortran.3.dylib /Applications/MATLAB_R2013b.app/sys/os/maci64/libgfortran.3.dylib
Restart MATLAB and try using the loadlibrary command to create the prototype file again. Do you still encounter the error message? If not, then the this is likely caused by a corrupt gfortran dynamic library in the MATLAB application directory.
in the case of using fink to install the gnu package on a mac its in the /sw folder. Otherwise the directions are the same.
A second way to resolve this is to add to the matlab search path in the startup file the location of the library.

I did try Nathan's suggestion, but didn't work. I' using MATLAB2013a, Xcode 5.1, and gfortran-4.8.
I had the same/similar problem because MATLAB only supports gfortran-4.3. I found this installer for Mac but it didn't work on my 64-bit version.
I solved the issue by using an earlier version (4.2.3) which you can download here gfortran-4.2.3.dmg or from this list. MATLAB gave me a compilation warning though, but I could execute my gfortran program with no further issues.

I had this problem when I ran fortran compiled stand alone programs from Matlab, i.e. MODFLOW and related programs, which I compiled on OSX some time ago. With R21014 I got an error message
"/Users/Theo/GRWMODELS/mflab/bin/mf2005.mac" mf2005.nam

From this it is clear that the dylib that comes along with Matlab and is used by Matlab as default does not hold the desired function and so is not compatible. I, however, have the correct dylib at some other location on my OSX. So I renamed the version in the search dir used by Matlab and copied my old version of dylab to that directory. This solved the problem.
This solution seems very practicle and logical as well.
