kactivities-4.13.0.tar.xz doesn't exist

[unix1]

kactivities fails to install because the URL specified in kactivities.rb - http://download.kde.org/stable/4.13.0/src/kactivities-4.13.0.tar.xz - results in a 404.

It looks like kactivities no longer exists in 4.14+ stable release versions. The last kactivities package is present in unstable/4.12.97. If I change the URL to that, it compiles, but going further, I get a very general and cryptic error while installing kde-runtime-4.14.3 (not sure if this is the symptom of outdated kactivities):

    -- Configuring incomplete, errors occurred!

with no further details in 01.cmake file.

I found an alternative url for kactivities 4.13.0: http://kde.mirrors.pair.com/Attic/4.13.0/src/kactivities-4.13.0.tar.xz
But also can not get kde-runtime to configure with the same --Configuring incomplete, errors occurred error.

However, a grep for Error through 01.cmake does find this:
