Ok. Here's version 2. Fixes are:
* Sorted the output by port number and removed duplicates. Duplicates
happen when a daemon listens on multiple IP addresses (samba is one).
* Skip non-existent processes
* remove (delete) from the end of readlink paths. This may happen if a
package has been upgraded and the old exe deleted.
* Use argv[0] if its an executable instead of /proc/pid/exe. This
makes daemons that are running under interpretters (perl, ruby, etc)
identified properly. In my case, postgrey failed, as a perl process.
* Ignore dpkg -S errors, and write a shorter line if there is no
package for the process.

What do you mean by -v option? If you mean run the exe with -v to get
the version, that could easily fail and do unpredictable things, as -v
is not standardised as a way to get the version of a program.
