Currently I can't compile the pango package with the current Haskell
Platform:
$ cabal install pango

Failed to install unix-2.6.0.1
cabal: Error: some packages failed to install:
directory-1.2.0.1 depends on unix-2.6.0.1 which failed to install.
pango-0.12.4 depends on unix-2.6.0.1 which failed to install.
process-1.1.0.2 depends on unix-2.6.0.1 which failed to install.
That is why I updated the bug with what you quote below. You say there is
no bug here. I didn't know that when I wrote the comment as there was a bug
reported with no indications that it was not a bug and I had the problem
described in the bug trying to do a cabal install of a Haskell package.
If I understand you correctly, since I am using the latest Haskell Platform
it seems pango should be trying to use unix-2.5.1.1 not unix.2.6.0.1. I
have no idea why it is not doing that.
The preceding is why I updated the bug two months ago.
As to why I was concerned about the forthcoming Haskell Platform, as I
wrote earlier in this thread: the bug mentions 7.6.3 as a milestone but
doesn't say it is closed or fixed in 7.6.3 although it does say that it
works in 7.6.1. At the time I started this thread my understanding was that
the forthcoming Platform was going to use 7.6.2 not 7.6.3.
Thanks
George
