Libical: Increasing Minimum Version Requirement

[Allen Winter]

Howdy,

For trunk, I plan to increase the minimum version requirement
for the Libcal package from 0.33 to 0.42.  Else the kdepimlibs
module will no longer build for you.

If your distribution does not provide version 0.42 (or higher)
then you will need to install it yourself from source, which can
be found at http://sourceforge.net/projects/freeassociation
(or ask you distribution to upgrade this package).

Note that you can tell the KDE buildsystem where your self-built
libical is installed by using the LIBICAL_BASE environment variable,
for example: export LIBICAL_BASE=/usr/local

I'll make this change on Monday 16 Feb.

Regards,
Allen, KDEPIM Module Coordinator
