This is really just a regex problem. What you did in perl is probably
really close to working in sed. If you would like help building the
regex, it would help to have more info on where the package name is
coming from. Since sed works on entire lines, the additional context
may require you/us to rewrite the regex if it is made to work with
only what you have given us so far. Here are some examples of possible
sources that I thought of. All of which would require slightly
different processing.
