runSalome and libssl.so.2 library

Hi to everybody!!

I have a problem when I try to run Salome.
First, I run the salome.sh script and later I run Salome with runSalome command. I get the following error message:

Searching for a free port for naming service: 2810 - Ok
Traceback (most recent call last):
  File "/home/misabel/salome/KERNEL_2.2.8/bin/salome/runSalome.py", line 761, in ?

    args, modules_list, modules_root_dir = get_config()

ImportError: libssl.so.2: cannot open shared object file: No such file or directory

I have looked for 'libssl.so.2' in /usr/lib directory and it is there, so I don't know what could be the problem.
I would be really grateful for receiving some advice.

Thanks!
