How to 'conditionally' use a specified module

Hello everyone,

I need to check if one of my variables is true, then use a specific
module:

my $use_cache = 'no';

if ($use_cache == 'yes'){
use Cache::SizeAwareFileCache;
}

The problem I have is that no matter if $use_cache is yes or no, Perl
always try to evaluate the use of Cache::SizeAwareFileCache at run-time
and if I don't have that module installed, it gives me an error:
Couldn't find the module "Cache/SizeAwareFileCache.pm".

Even though I stated clearly that $use_cache = 'no', Perl still reports
that Cache::SizeAwareFileCache is not installed.

What exactly am I missing here? Is there an easy way to ignore the
missing module inside a condition?

Thanks
