I now have it working for static-static on Linux; but not with
dynamic anything yet. Thanks for all your help.

Assuming this is a pure interface, you need one more thing:

Hi,
Suppose I want the following functions:
newRef :: a -> RefMonad (Ref a)
readRef :: Ref a -> RefMonad a
writeRef :: Ref a -> a -> RefMonad ()
for some appropriate data Ref = ...
Obviously these functions are already satisfied by IORefs and STM.

Hi cafe,
There are a lot of http servers in hackage. I didn't have used none.
I would like to know if one of them is something closer of the nginx.
I need some light and fast. It don't need support all http, just the basics is
fine.
Suggestions?

I'm working in a program where I use many connections with Network.HTTP.

All I need is to handle this error. The function 'catch'

Correct. About a week-ish ago I submitted a patch to update the docs.

There is no guarantee that /Developer-old/ is still on the system, so depending
on it for symlinking is probably not a good idea. So far I have had no problems

This could be one alternative. However, separate Snow Leopa
ok, now I've installed XCode 4 and run into the very same problems.
As already said, XCode 4 targets snow leopard only. That's why the
MacOSX10.5.sdk is missing. unfortunately the ghc packages for snow leopard
are configured to support leopard still.

Hi Don,
What would be a good way to figure out the usage of ByteString -
particularly the PS constructor.
