error loading the library "McsUsbDLL" with Matlab R2009b (Mac)

Hello,

i am working with a matlab script created on windows by a colleague and used for several years on PCs
and I am experiencing problems with a function that loads the McsUsbDLL library:

I got the following errors using matlab R2009b (mac):

??? Error using ==> loadlibrary at 474
There was an error loading the library "McsUsbDLL"
dlopen(McsUsbDLL.dylib, 1): image not found

Error in ==> ICSS_Training at 28
 loadlibrary('McsUsbDLL', 'McsUsbDLL.h','alias','McsUsbDLL')

Caused by:
   Error using ==> loaddefinedlibrary
   dlopen(McsUsbDLL.dylib, 1): image not found


I also tried, before using Matlab 2009b, to run the program with Matlab R2011a
I got then the following errors:

??? Error using ==> loadlibrary at 441
Failed to preprocess the input file.
Output from preprocessor is:/bin/bash: gcc-4.2: command not found

Error in ==> ICSS_Training at 28
 loadlibrary('McsUsbDLL', 'McsUsbDLL.h','alias','McsUsbDLL')

I thought the problem was a incompatibility of the script with the 64bit architecture of the R2011a version
so I tried with the R2009b working on 32bit but the problem remains even if the errors slightly differ.

I would be grateful to receive more insights and helps on this problem!
Thank you in advance

The McsUsbDLL.dll work only on Windows operating system.
