The current source won't build for me with ghc 6.8.2 after a `make
distclean', even with `configure --disable-mmap':

  [ghc] .depend

  Src/ByteStringUtils.hs:96:7:
      Could not find module `System.IO.Posix.MMap':
        Use -v to see a list of the files searched for.
  make: *** [.depend] Error 1

I assume this is something added in a later ghc, but are any other
details relevant?  I'm using GNU/Linux.

Thank you for this report. Could you tell us, please, the current source that 
you mention, which source is that, exactly? And also, have you tried the new 
cabal-based build system? I am not into all the details myself, but there is a 
description in the README file of the http://darcs.net repository that may help.

Best regards
Thorkil

The darcs repository, maybe half an hour before I sent the message.

I followed the recommended procedure with autoconf, which is the (only)
one that works with the packages in Ubuntu.  That way of building broke
within the last two weeks, I think.  If you know where to find that
module in Ubuntu 8.10 packages, I'd be happy to know, but --disable-mmap
rather implies it avoids it.  Exactly what is it supposed to do?
Otherwise, where do I get the mmap module, if it's required?  I don't
know my way around ghc and other Haskell stuff (but not through lack of
good taste, I hope).

I think this is a duplicate of issue1347.  Thanks!

Sorry, I thought I checked before submitting it, in which case I don't
know how I'd have missed the other one...

If I understand this correctly, I'll send a patch later.

I'm confused how it is supposed to build.  README says autoconf is
recommended, contrary to what #1347 says, and now that I realize I can
do it, the cabal build also fails.
