[Ipopt] IPOPT on Mac OSX 10.6 with MATLAB R2011b

[Ray Zimmerman]

Looks like it is trying to dynamically link to ...

    libipopt.1.dylib
    libcoinhsl.1.dylib
    libcoinmetis.1.dylib

... when it should be statically linking to them. In fact, these files shouldn't even exist ... maybe they are still around from a previous build?

Try deleting those libraries (or starting with a clean Ipopt build directory) and rebuilding Ipopt and the MEX file, then hopefully it will link to the static files and Matlab will be able to load everything it needs to run properly.
