********************************

* **start up of khal and ikhal is very slow**

     In some case the pytz (python timezone) is only available as a
     zip file, as pytz accesses several parts during initialization
     this takes some time. If *time python -c "import pytz;
     pytz.timezone('Europe/Berlin')"* takes nearly as much time as
     running khal, uncompressing that file via pytz via *(sudo) pip
     unzip pytz* might help.

* **ikhal raises an Exception: AttributeError: 'module' object has
  no attribute 'SimpleFocusListWalker'**

     You probably need to upgrade urwid to version 1.1.0, if your OS
     does come with an older version of *urwid* you can install the
     latest version to userspace (with out messing up your default
     installation) with *pip install --upgrade urwid --user*.

* **Installation stops with an error: source/str_util.c:25:20: fatal
  error: Python.h: No such file or directory**

     You do not have the Python development headers installed, on
     Debian based Distributions you can install them via *aptitude
     install python-dev*.
