Vuescan problem

I run SuSE8.1 Linux. I was using Vuescan7.6.72 which was running OK. I wanted to upgrade to Vuescan7.6.78, but when trying to run this version of vuescan I got the following error message: ./vuescan: /lib/libc.so.6: version `GLIBC_2.3' not found (required by ./vuescan) How do I resolve this? I didn't find it on my SuSE8.1 DVD either. (Installing the old Vuescan7.6.72 again and this version runs fine again). Kind regards, -- Frits Wüthrich
