Got it installed and configured... had to change the format of the conky.conf file to the new format to prevent it reporting errors (and which made it start up faster):
I've since changed the layout of conky a bit to tighten up the space taken (it now takes only half the vertical height as the image above, while showing the same information), here's my conky.conf:
I also start conky a bit differently, using nice to give it low priority, and I've set my CPU governor to ignore-nice-load, so conky doesn't increase CPU frequency.
[EDIT]
For those who want Conky to portray a calendar: ${color 000000}${texeci 1800 cal}
You can issue the cal command in terminal, as well.
