Hi Mahsa -

When I've seen problems like this before it's because the executable is linked against a library that gets moved or upgraded or something; so it's usually easy enough to find where the library is pointed, and move/install/rename the library to the spot where the executable is looking for it. In your case, though, there are a couple of library files the executable wasn't told about:

libgsl.so.0 => not found 
libgslcblas.so.0 => not found

That looks like those are part of the GNU scientific library:

[www.gnu.org]

I'm guessing you don't have root access to your machine, so the best bet is to tell your sysadmin that you need that software installed; assuming your LD_LIBRARY_PATH environment variable is in order, that will probably take care of your problem. If you do have root access to your machine, but don't know what I'm talking about, find a UNIX guru to help you get that thing installed, and your dynamic library path updated appropriately. Such a process is beyond the scope of what can be answered in this forum, but you can check these pages for an overview of the issues in play:
