Hmm. How sure are you that it was cabal that created the package.conf file? This is the code that does so, and it definitely seems to add a newline:

This is on Mac OS X, and it's definitely Setup.hs that's creating the file, and it definitely has just "[]".

Transcript (prompt reduced to "$ " for brevity):

It's not a newline issue, something else strange is going on here. Your local package.conf is being created by ghc-pkg (which is a little eager to create it in 6.4; 6.4.1 will be better). The parse error is coming from Cabal (Distribution.Simple.Configure) which is having trouble parsing the list of packages from ghc-pkg list. Could you post your output from "ghc-pkg list" after running the configure step above? Cheers, Simon
