LoLShield Charlieplex library conflict with DS3231 (Chronodot)

[GoogleCodeExporter]

What steps will reproduce the problem?

When I load Charlieplexing.h and Wire.h, and then call the req'd 
"LedSign::Init()" in the void.setup(), it seems the sketch crashes.

In the code example below, when the LedSign::Init is commented out, The Serial 
Monitor shows:

init           (command before the fouling Init)
made it        (command following the fouling - but commented out- Init)
get time       (the proper operations in the loop())
...
...  and works properly (it won;t show every second, as there are a number of 
debugging delay() statements)

When LedSign::Init() is active,  all I get in the serial monitor is:

init                        command before the fouling Init
                              ...
                              (chirping crickets)
                              ...

1. any arduino I have (Mega, Duemillablahblahblah, and ProMini5/16
2. Macetech Chronodot
3. charlieplex network w/ 72 LEDS

What is the expected output? What do you see instead?
i am expecting to see lights.  the sketch seems to freeze once either: 
Charliplexing or Wire gets init'ed/started.
see below..

What version of the product are you using? On what operating system?
Win7
arduino IDE 1.0 & 1.01

Please provide any additional information below.

still no takers?  
I read somewhere that lolshield is incompatible with arduino1.01

hey, I have the same issue. I've sent an e-mail, did you solve it?:)

in the Charliplexing.cpp (sic) is a bug. during Init the function SetBrightness 
is called which contains Serial.end(); delete it - it is not needed! actually 
it doesnt make a bit of sense.
see: Issue 31

in general the library at its current state is a complete mess. i'm sorry, but 
it's so hard to read, unfinished and incompatible with the Mega and Leonardo at 
least

I removed the Serial.end() in revision 28.  I don't have a Chronodot to test 
with, though.

Also, re mrvisual, I added Mega support in revision 30.
