How about this?

my $value = "8:0:20:0:2:10";

print join "", map { sprintf "%02s", $_ } split /:/, $value;

or 

print sprintf "%02s%02s%02s%02s%02s%02s", split /:/, $value;

Updated as per merlyn's and sauoq's comments below (changed %02d to %02s).

 

perl -le 'print+unpack("N",pack("B32","00000000000000000000001000010100"))'
