I got the grucial concept before asking, but it was still shadowy to
me how to make things work reliably.

We could somehow then offer an "official" tree containing the sum of
all single packages kept to an older version, I fear that despite the
efforts older architectures will need to be remain back. Even though
the fantastic effort of you and friends to five us oupdated compilers
and such, the Foundation and AppKit remains fixed.

That is all clear. Part of my issue is how to get a certain version.
Right now I solved my case this way
1) create local repository
2) create gimp and gimp2 ports by manually downloading the files from
the macports repository at the "point" it transitioned from 2.8 to
This is of course a bit tedious, it was manageable for a couple of
patch files, but will need manual work to cherrpyick eventual

Yeah clear, it is a priority list. Since macports doesn't have really
versions (except if two distinct packages exist) it works, but can of
course caouse incompatible dependencies, causing then the need to go
up the tree with releases.

I will, up to know I only have one port and it worked too! But I bet
it will grow and perhaps I shall offer it to github.
