I dont know about centOS but it seems similar to the way you install on ubuntu.
1.Extract and THEN GO THE DIRECTORY IT IS EXTRACTED( you seem didnt do that (cd LifeScope-2.5.r0-97271_20111110010925))
2.in ubuntu you type: ./configure
3.make
4.make install
cd directory-where-code-is-to-build
su
make install
exit
"su" will ask for the root password. Don't add a dash after 'su' since you want to stay in the build directory to run "make install". As "su" creates a new shell, the "exit" command will return you to the user environment.
