How to startx KDE Plasma 5.9.2

[Geordie]

You don't make it easy

http://area51.pcbsd.org/trunk/area51
/x11/plasma5-plasma-desktop does not exit
so next try

svnlite checkout https://src.mouf.net/area51/browse/branches/plasma5/KDE

I get this

svn: E170013: Unable to connect to a repository at URL
'https://src.mouf.net/area51/browse/branches/plasma5/KDE' svn: E130005:
XML Parsing failed: Unexpected root element 'html'

any suggestions
