Have to see.
We would need to put the generated binary somewhere and use that one for the actual/final build from the Portfile. That would speed up things for everyone ... > I think this might deliver a newer ghc 8.6.3 for older systems (actually > 8.8.1 is out now, so I might just go all the way to there) and then once we > have a bootstrap we can just use the current haskell infrastructure & stack. > On the way-out-there fringe, who knows about i386: There is an 8.8.1 i386 > bootstrap binary for debian, so it appears possible to ponder that, at least. On 10.6 it might in fact be possible to cross-compile for both i386 and PPC. At least their official suggestion is to cross-compile from a platform that already works. Mojca
