Problem installing new version of Sophos

[Howard Robinson]

Hello
I am trying to install the latest Sophos.
I am using the same method I have used for a few years and not had problems until this time.
(I know MailScanner needs updating as it's a year or so old - it's on  a long list of jobs to do!) 

I have downloaded the linux.intel.libc6.tar.Z file to /tmp and run /usr/sbin/Sophos.install
I get the following out put.

[root at server tmp]# /usr/sbin/Sophos.install

If you are trying to install Sophos version 5,
then please expand the tar file with a command like
    tar xzf sav-linux-5-i386.tgz
    cd sophos-av
Then run me again!

Press return to continue, or Ctrl-C to escape.

Could not calculate Sophos version number,  at /usr/lib/MailScanner/sophos-autoupdate line 152.
Done.
[root at server tmp]# /
It is the right version according to the note I have done on previous updates - I tried the glibc version to check and that failed with the same error!

Any Pointers on this?
I'll have a trawl on the web now but thought someone might be able to point me directly to the correction of problem.
Thanks.
