Could you try to reinstall package containing missed
/usr/lib/i386-linux-gnu/egl/egl_gallium.so with
sudo apt-get install --reinstall libegl1-mesa-drivers
?
Did you try to install scilab 5.3.3 from ubuntu repositories (sudo apt-get
install scilab)? Does it work?
Manual unpacking 5.5.1 to /usr/local may cause missed system dependencies.
On my ubuntu I have many scilab versions - 5.3.3 from repository and newer
versions (unpacked to ~/Software with custom launchers on desktop).
