I believe to know who you are. The temperature in Buenos Aires is also not so fresh...
Through your Wiki Page I found this Conky.
Maybe you can have a look at it, to see where the error is in the script, because the rings do not appear.

Ring Meters by londonali1010 (2009)
This script draws percentage meters as rings. It is fully customisable; all options are described in the script.
IMPORTANT: if you are using the 'cpu' function, it will cause a segmentation fault if it tries to draw a ring straight away. The if statement near the end of the script uses a delay to make sure that this doesn't happen. It calculates the length of the delay by the number of updates since Conky started. Generally, a value of 5s is long enough, so if you update Conky every 1s, use update_num > 5 in that if statement (the default). If you only update Conky every 2s, you should change it to update_num > 3; conversely if you update Conky every 0.5s, you should use update_num > 10. ALSO, if you change your Conky, is it best to use"killall conky; conky" to update it, otherwise the update_num will not be reset and you will get an error.

To call this script in Conky, use the following (assuming that you save this script to ~/scripts/rings.lua):
lua_load ~/scripts/rings-v1.2.1.lua
lua_draw_hook_pre ring_stats
Changelog:
+ v1.2.1 -- Fixed minor bug that caused script to crash if conky_parse() returns a nil value (20.10.2009)
+ v1.2 -- Added option for the ending angle of the rings (07.10.2009)
+ v1.1 -- Added options for the starting angle of the rings, and added the"max" variable, to allow for variables that output a numerical value rather than a percentage (29.09.2009)
+ v1.0 -- Original release (28.09.2009)

--"name" is the type of stat to display; you can choose from 'cpu', 'memperc', 'fs_used_perc', 'battery_used_perc'.
name='time',
--"arg" is the argument to the stat type, e.g. if in Conky you would write ${cpu cpu0}, 'cpu0' would be the argument. If you would not use an argument in the Conky variable, use ''.
arg='%I',
--"max" is the maximum value of the ring. If the Conky variable outputs a percentage, use 100.

--"bg_colour" is the colour of the base ring.
bg_colour=0x05ffff,
--"bg_alpha" is the alpha value of the base ring.

--"fg_colour" is the colour of the indicator part of the ring.
fg_colour=0xffffff,
--"fg_alpha" is the alpha value of the indicator part of the ring.

--"x" and"y" are the x and y coordinates of the centre of the ring, relative to the top left corner of the Conky window.

radius=59,
--"thickness" is the thickness of the ring, centred around the radius.

--"start_angle" is the starting angle of the ring, in degrees, clockwise from top. Value can be either positive or negative.
start_angle=0,
--"end_angle" is the ending angle of the ring, in degrees, clockwise from top. Value can be either positive or negative, but must be larger (e.g. more clockwise) than start_angle.
