Hi Guys, I have got a situation where I want to use Digest::MD5 module for calculating checksums, but not all of the machines in my environemnt have this module especially older perl verisons. So, I decided to go with the solution to load this module only if its installed on the machine otherwise use '/usr/bin/cksum' to calculate the checksum. I used something like below to achieve this: 
if (eval {require Digest::MD5})
{
my $flcn=Digest::MD5->new();
..
..
}
else
{
my cksum=`/usr/bin/cksum $file`;
.
..
}

This seems to work fine. Now, my question is this that is this right to use this kind of invocation. Can I get problems in some other perl versions if I use this? What kind of effects does this have on the program? Is there some better way to load a particular module only if its installed on a machine?
