RFE: add a "depends_pkg" type of dependency

[cooljeanius (Eric Gallager)]

I'd like to be able to declare a dependency on stuff like dylibbundler or jarbundler just for the packaging step, so that I could bundle up everything into a single app bundle instead of having the installer put a bunch of stuff in /opt/local. In other words I'd like something like this to work:

depends_pkg dylibbundler
pre-pkg {
    dylibbundler -x ${destroot}${applications_dir}${name}.app/Contents/MacOS/${name} -b -cd -p @executable_path/../libs
}

So installing a pkg of the port would give you something different than port install? That doesn't seem like a very good idea.

[cooljeanius (Eric Gallager)]

No, this would be for packaging stuff for users that don't have MacPorts installed. Isn't that what the port pkg command is for in the first place?

[ryandesign (Ryan Carsten Schmidt)]

Yes but right now "port pkg" runs "port destroot", then creates a package of that destroot. That's what we want; that's what ports do. I can see the value in what you're talking about, if I wanted to distribute some standalone packages, and I might use that technique (running dylibbundler in pre-pkg) but I wouldn't commit that to the main ports tree (I'd keep private modified ports with those changes). And since I'd only be using this on my system, it wouldn't be a problem for me to need to manually install dylibbundler first.
