The class is in the jts-1.10.jar from the GeoTools repo. If you're
using maven you should get it automagically. Alternatively you can
download it from here...

http://download.osgeo.org/webdav/geotools/com/vividsolutions/jts/1.10/jts-1.10.jar

PointPairDistance is in package
com.vividsolutions.jts.algorithm.distance (as is the
EuclideanDistanceToPoint class).  I just checked the jts-1.10 jar and
both classes seem to be there.
