esorepo gcc8, gcc9 Monterey

[dnfarias]

Hi all, a new MacOS user here. I have Monterey 12.2.1 version, with Macports 2.7.1-12. I've seen several tickets related to building gcc8 and gcc9 on new OSX versions, although I'm unsure on how to fix this problem with esorepo port. In particular, I was trying to do:

sudo port install esopipe-molecfit 

(it happens for other esopipe packages), and it fails at installing libgcc8 and libgcc9. In specific, the same issue as other tickets is:

From the patches and fixes, I suppose it shouldn't be hard to make this work.
