Why removing anything while installing new packages. Downgrading i could
understand if binaries are involved, but removing?
Sorry but pkg is only usable to install or update things if you only use
pkg. Installing packages via port kills pkg.
And BTW the same command has installed the correct package since pkg
exists. So flavors haven't improved anything here.
As said I'm doing this since mid 1990s and rely heavily on pkg when
installing new systems. Worked like charm since it arrived but only for
fresh install. After some month of updating and installing via ports the
problems shown above start to appear.
So i hope the portupgrade guys are fixing this soon.
