OK. Now we're getting somewhere.
The way your log file changes indicates that you have made some config
changes to Apache, some of which may have been a bad idea. Assuming that you
are able to execute cgis from where you have smokeping.cgi, this bit is a
giveaway:

Most particularly this line:
> > Can't locate lib.pm in @INC (@INC contains:

In the 'use lib' statements (particularly line 4) of smokeping.cgi,
something is not quoted properly and the system is looking for 'lib.pm'
instead of the named module.
The two lines likely to cause the problem look like this on my machine:

use lib qw(/usr/local/rrdtool-1.0.42/lib/perl);
use lib qw(/smokeping/lib);

I have encountered this problem before, but I can't remember exactly what I
did to fix it. Hope this helps.
