Permissions issue was straight-forward to resolve.
Yesterday I tracked this down to a conflict with versions of
bytestring.
ghc.6.10.4 needs bytestring-0.9.1.4
ghc-pkg: unregistering
bytestring-0.9.1.4 would break the following packages: ha
ddock-2.4.2 ghc-6.10.4
Win32-2.2.0.0 regex-base-0.72.0.2 regex-posix-0.72.0.3 re
gex-compat-0.71.0.1
zlib-0.5.0.0 HTTP-4000.0.6 cgi-3001.1.7.1 curl-1.3.5 QuickCh
eck-2.1.0.3 tagsoup-0.9
feed-0.3.7 tagsoup-0.10 utf8-string-0.3.6 xml-1.3.7 (use
--force to override)
other libraries need bytestring-09.1.6
ghc-pkg: unregistering
bytestring-0.9.1.6 would break the following packages: Wi
n32-2.2.0.0 Win32-2.2.0.2
HTTP-4000.0.9 (use --force to override)
Yesterday I could not access haskell.org to see if I can
install a newer version of GHC - network or server is done.
Today I am upgrading everything to ghc-6.12.2
There must be a tool somewhere that can assess potential
conflicts :
A needs B (>2)
A needs C (>1) but
C needs B (<2)
I will look once I get passed these install issues

Subject: [Haskell-cafe] Installing Curl on Windows 7 - permissions
problem
Don,
More angst with Windows 7 permissions. I hope this
is a simple thing for you or someone else to help me with.
I have successfully installed other packages into my
private cabal area.
When it came to the Haskell curl package, I got
permission errors.
Just to prove that things go to the right places, here is
a successful run with the Parseargs Package.

Parseargs installed fine and the package list shows it in

C:\Users\Ralph>
Now for curl.
I installed Mingw32 (following the advice at http://old.nabble.com/cURL-under-Windows-again-td21789068.html#a21789068)
This is what happened when I went to my windows shell:
C:\Users\Ralph\AppData\Roaming\cabal\curl-1.3.5>runhaskell
setup build
Preprocessing library
curl-1.3.5...
Building curl-1.3.5...
Registering curl-1.3.5...
C:\Users\Ralph\AppData\Roaming\cabal\curl-1.3.5>runhaskell
setup install
setup: permission denied
I am wondering if the curl package is trying to put
things in system folders?
Help much appreciated - tight deadlines
Ralph

Yes, see:
Network.Curl.Download.Lazy.openLazyURI
though I think it is possible that I strictified the
code. Have a play
around with it if it doesn't meet your needs -- should be
/trivial/ to
ensure it is chunk-wise lazy.
