two version of a package still exits after removing

I installed version 0.4.7 of "ucto"- a unicode toknizer in my ubuntu machine and removed it and
I install version 0.5.3 from ubuntu repository. The problem is when I try to compile "frog" package from the source
the compiler detects older version of "ucto" and the compiler complains that frog requires version of ucto >= 0.4.9 but version 0.4.7 exist in your system.

I removed by using the command sudo apt-get purge ucto, sudo apt-get remove ucto ,
sudo apt-get --purge remove ucto and succesfully removed but when I run
apt-cache show ucto | grep Version it displays the following
Version: 0.5.3-2~raring1
Version: 0.4.3-1build1

so how can remove these and able to compile other packages that needs newest version of "ucto"
or how can I force the compiler to use the newest version . please any help ! I am confused
Thanks
