Don't the both of you mean?:

$ dpkg -s  <packagename / packagenam* / | grep packagename>

dpkg with the -l option just lists some information about the package,
but unless I'm missing something, it doesn't actually indicate whether
you have the package installed on your system.

>From the man page:

dpkg -l | --list package-name-pattern ...
     List packages matching given pattern.
dpkg -s | --status package-name ...
     Report status of specified package.
