I'm surprised this works at all - it certainly isn't doing what you think it is. The : 

while(<@source>)
{
  ...
}

[download]
is actually doing a glob based on the contents of the file and is making $_ the actual line where (not unexpectedly) there isn't a match.

I think you meant: 

foreach ( @source )
{
   ...
}

[download]
or 
while(<SOURCE>)
{
   ...
}

[download]
if the latter you will need to move the close to after the loop.
