Using mcc to compile code which calls mex files

I need to compile code which calls an outside function (GAMS) using mex files. I can compile the code with mcc and receive no errors. However, when I run the executable I get the following error,
sh: gams: command not found
Could not run (null): check gams.path
Error in ==> multistart_GAMS_initializer_v2_1>(parfor body) at 521
Error in ==> parallel_function at 477
Error in ==> multistart_GAMS_initializer_v2_1 at 501
Error in ==> restart at 7
MATGAMS:exec
where gams is the mex file calling the outside program.
gams is in the system folder containing the program, GAMS, to be called. The file pathdef.m is included in the folder from which matlab is being called so that the folder containing gams is on the matlabpath.
This code runs fine when it is not compiled.
My compile command is as follows:
/opt/MATLAB/R2011a/bin/mcc -m -a /opt/gams/23.5.1/gams.m -a /opt/gams/23.5.1/wgdx.m -a /opt/gams/23.5.1/writegdx.m -a /opt/gams/23.5.1/rgdx.m -a /opt/gams/23.5.1/readgdx.m -a /opt/gams/23.5.1/full2sp.m -a /opt/gams/23.5.1/sp2full.m -a /opt/gams/23.5.1/gams.mexa64 -a /opt/gams/23.5.1/gdxInfo.mexa64 -a /opt/gams/23.5.1/rgdx.mexa64 -a /opt/gams/23.5.1/wgdx.mexa64 -R -nodisplay -R -nodesktop

The error says "sh: gams: command not found" - so it seems like the "outside" program is not on the System path?

Tricia: Sorry, I've run out of ideas. Perhaps you should contact MathWorks Tech Support to see if they have any ideas?

Hi,
if you look into the file "multistart_GAMS_initializer_v2_1" that (from your error message) tries to start gams: does it do anything to the system path there? Or does it start some local shell script there (gams.sh or whatsoever) which is not there in the compiled application?
