You really don't require a full-fledged Perl program for that, but anyway -

Code:
$ 
$ 
$ cat -n f12
     1    :: gstreamer
     2    :: xine-lib
     3    :: xine-lib-extras
$ 
$ 
$ cat -n f12.pl
     1    #!/usr/bin/perl -w
     2    $file = "f12";
     3    open (F, $file) or die "Can't open $file: $!";
     4    while (<F>) {
     5      chomp;
     6      s/^[: ]+//;
     7      $x = ($. == 1) ? $_ : "$x $_";
     8    }
     9    close (F) or die "Can't close $file: $!";
    10    print $x,"\n";
$ 
$ 
$ perl f12.pl
gstreamer xine-lib xine-lib-extras
$
