Scilab 5.3.1 execution error on RHEL 5.5

[huub]

Hi,

I just installed the tar-ball of Scilab 5.3.1 on RHEL (actually, CentOS) 
5.5, and get this when starting:

scilab-bin: /lib/libc.so.6: version `GLIBC_2.7' not found (required by 
/opt/scilab-5.3.1/lib/thirdparty/libhdf5.so.6)

Is there a solution for this?

Thanks.
