You have to (re)build root after you have installed libPythia6. Only if this library is found during the build process, the libEGPythia6 is being built. The binary from the root website does not include it as you found out.

Or, if you have Fink (http://fink.sf.net) installed, you could install the package root4-cernlib, which will install a root version with libEGPythia6.
