Updated the initial comment to address the change request

[raimue]

This does not yet address my requests. I was talking about the commit message, not the comments on GitHub. You will need to edit the commit itself. Go to your local branch from which you started this pull request, edit the commit message, than overwrite the existing pull request.

Assuming remote origin refers to your repository emaros/macports-ports on GitHub, and upstream refers to macports/macports-ports:

# switch to branch
git checkout ldas_tools_pkgconfig_update
# open editor to make changes to commit message
git commit --amend
# optional: rebase your changes on top of current master
git remote update
git rebase upstream/master
# update pull request
git push --force origin ldas_tools_pkgconfig_update

@larryv extended the wiki page on CommitMessages with more details while this pull request was open. I fixed your commit message to fit into 50 characters and wrapped the body at 72 characters.

Thank you for the contribution.
