MATLAB toolbox not working with SUNDIALS 2.7.0_2

[gpavanb-old]

Cantera version

2.3.0

Operating System

Mac OS X

Python/MATLAB version

2.7
MATLAB R2014b

Expected Behavior

MATLAB toolbox invoked

Actual Behavior

Invalid MEX-file '/Users/gpavanb/Cantera/lib/cantera/matlab/toolbox/ctmethods.mexmaci64':
dlopen(/Users/gpavanb/Cantera/lib/cantera/matlab/toolbox/ctmethods.mexmaci64, 6): Symbol not found: _CVLapackBand
Referenced from: /Users/gpavanb/Cantera/lib/cantera/matlab/toolbox/ctmethods.mexmaci64

in /Users/gpavanb/Cantera/lib/cantera/matlab/toolbox/ctmethods.mexmaci64

Error in adddir (line 11)
ctmethods(0, 3, d);

Steps to reproduce

1. Install Cantera 2.3.0 with latest Sundials 2.7.0_2
2. Enable MATLAB toolbox. Using scons to build and install
3. Error on invoking any Cantera statement, e.g. gas = Solution('gri30.cti','gas')

Unfortunately, this is a well known issue with Matlab on all platforms. Since Matlab includes its own shared libraries for SUNDIALS, we usually recommend that users don't link to SUNDIALS when they use the Matlab toolbox. In fact, the official installation instructions for Homebrew on OS X explicitly state that SUNDIALS inclusion is turned off when building the Matlab interface (see item 3 on that list). Do you need SUNDIALS support for a particular use case?

I guess we should disable linking to an external SUNDIALS library when compilation of the Matlab toolbox is enabled, the same way we do for the external BLAS/LAPACK libraries.
