Can't find NTOP in the list of available packages

[ekhaskel]

Recently installed Pfsense 2.1-RELEASE (i386)
Wanted to add ntop package, but don't see it in the list of available packages. How may I install the ntop package?
Thanks

It is not supported on embedded installs (NanoBSD) so it does not appear in the list on those installs:
