CANNOT EXECUTE UNIX BINARY

Hi,
Please help me here. I am on a Solaris 8 machine
without root access and want to run this tool locally.
This is what i did
- Went to http://www.everybuddy.com/en/download.php
 and downloaded Binary (.tar.gz 0.4.3-18) 
 actual filename was everybuddy-0.4.3-18_rh80.tar
- i untarred it and then tried to execte the file
./usr/local/bin/everybuddy..
- The error i got was the following
./usr/local/bin/everybuddy: Exec format error. Binary
file not executable

COULD SOMEONE PLEASE TELL ME WHAT I MAY BE DOING WRONG
OR DO I NEED A NEW BINARY FOR SUN SOLARIS 8
WITH THANKS
JAY
