Thanks Claus, Your condensed summary was my understanding, but if I try to issue Cabal install --reinstall cmu It works every time from a MSYS shell, but with Cygwin I get Linking dist\build\cmu\cmu.exe ... C:\Program Files\Haskell Platform\2010.1.0.0\lib\..\mingw\bin\windres: can't open temporary file `\/cca04932.irc': No such file or directory cabal.exe: Error: some packages failed to install: cmu-1.2 failed during the building phase. The exception was: ExitFailure 1 ('cmu' is just an example; the same behaviour seems apparent whatever the package; I see something very similar when I ask GHC to compile hello.hs.) The general answer I seem to have been getting (and responses I have seen elsewhere top this problem) is 'don't expect the Haskell tools to work with Cygwin'. At any rate it seems that, for some people at least, the latest version of the Haskell tools won't work when launched from Cygwin Bash.

Thanks Stephen--that was related to my original question, about using HP with Cygwin. The answer seems to be No!--you must use MSYS (for real work).
The short version: - Cygwin provides commandline tools, compilers and libraries - MSYS provides commandline tools for the MinGW compilers and libraries You can use the commandline tools from either Cygwin or MSYS, but you need to compile and link with the compilers and libraries from MinGW. Cygwin's gcc produces binaries that live in a unix-emulation on top of windows, and depend on a cygwin dll to act as a translator. MinGW's gcc produces native windows binaries.
