Yes. It is used by libkcal though; it is a replacement for the old internal version of libical. Trust me; it's much better this way--the old integrated libical had many bugs, including random changing of Korganizer appointment times.
Shouldn't libical then be in the dependencies section of svn?
Look for the .tar.gz file--it is in that list somewhere.
I'm still unclear -- are those two packages required or optional for building kdepim? If they are required, then like libical, shouldn't they be in svn/dependencies?
Yes it would. However, security certificates cost money. Lots of it. Unless someone would like to donate a site-wide certificate for *.quickbuild.pearsoncomputing.net, I don't think that will change. ;-)
I just dislike the way Firefox does not allow the option to accept the certificate. Yet Another Example of Arrogant Developers.
