Why there are so many binary packages missing on FTP?

[Yuri]

/usr/ports/UPDATING recently recommended to upgrade kde-4.1.0 to kde-4-2.0.

So I deleted kde-4.1.0 only to find out that there are no binaries for 
both kde-4.1.0 and kde-4.2.0.
So I had to build kde-4.2.0 for many hours, again, only to find out that 
it doesn't work as well as kde-4.1.0.

"Desktop Folder" applet doesn't show anything for ke-4.1.0. Applets show 
contents of other folders
but there are no scrollbars in them. Also bottom panel doesn't have any 
colors and looks ugly.

So now I a stuck with broken kde-4.2.0 and there is no easy way to go 
anywhere.

I sent similar question to kde at freebsd.org but got no answer.

So why kde-4.1.0 and kde-4.2.0 binaries are missing on FTP?
And does kde4-4.2.0 work for anybody?
