Who renamed it? It's still called System.Posix AFAIK.
tar references System.PosixCompat, which apparently comes from a
library
called unix-compat. I have no idea why the lib isn't just called unix
and the modules not System.Posix.*, for tar works fine with
System.Posix.*.
The tar package uses System.PosixCompat from the unix-compat package
to also work under non-posix systems (read Windows). This dependency
is listed in the tar.cabal file (see http://hackage.haskell.org/
packages/archive/tar/0.1/tar.cabal). System.Posix was never renamed.
The main problem you seem to be running into is that base previously
contained bytestring, but you need to upgrade bytestring in order
to use
binary, right?
Actually I'm more annoyed by the many small and unneccessary stumbling
blocks right now. I mean, you could easily put an instruction into
the
INSTALL file that says "if you're on GHC 6.4 or 6.6, register this
replacement configuration for base to sanitize it". You cannot write
"if you're on 6.4, edit all references to System.PosixCompat,
unless you
already installed unix-compat, and you absolutely need binary 0.4,
unless you're on 6.4, where you want binary 0.3 but need to patch
it so
it has instance MonadFix Get, etc. pp." there, since something like
that
just pisses off your users.
Why not just install unix-compat? It is listed as a dependency after
all.
I seem to be able to build the tar package against binary-0.3. What
exactly is the error that you are getting?
By the way, I don't think that users of open source software have a
right to be pissed off, or at least authors don't have an obligation
to care about them being pissed off. What users do have is a right to
submit patches.
That said, I agree that the constantly changing packages make it hard
to keep dependencies up to date. I guess that this is price we pay
for moving quickly. At some point, however, we will have to stop
breaking things.
