You could make Configuration.pm not a package in itself, but just contain the 
corresponding variable declarations. Here's what I have done in some programs 
that require a configuration file. The file is called Config.pl, and it only 
contains the following:

#---------- start of Config.pl
%Config=(
	param1 =>  value1,
	param2 =>  value2,
	...
	);

1;
#----------- end of Config.pl

Then in the main program I do:

eval 'require "Config.pl"';
die "Error: $@" if $@;

and then I can just use $Config{param1} etc to access the configuration 
parameters. I use a hash, but you could just as well use simple variables like 
@Site, @Semaphore, etc.

Hope this helps,
