[Haskell-cafe] I do not want to be a bitch, but ghc-6.8.3 and haskell binary policy are really horrible.

[Magicloud]

Sorry, let me say it this way:
1. Ghc cannot be bootstrap-installed. And the ghc-6.8.3 binary from 
official website also cannot run in my box, some kind of overflow error. 
So I have to look for help, a few hours later, I found 6.4.2 (I am not 
sure) which runs well in my box, and install ghc-6.8.3 indirectly.
2. After `cabal update && cabal upgrade`, ghc-6.8.3 cannot be built. Lib 
Network.URI cannot be compiled because:
Network/CGI/Protocol.hs:41:0:
   Failed to load interface for `Network.URI':
     Perhaps you haven't installed the profiling libraries for package 
network-2.2.0.0?
     Use -v to see a list of the files searched for.
I remove this SUBDIRS from the Makefile, luckly, it works. A few more 
hours lost in my life.
3. When I `ghc -v`, there are lots of "hiding package xxx to avoid 
conflict with later version yyy", do I have a way to remove these hiding 
packages? And "package xx will be ignored due to missing or recursive 
dependencies: yy", what does this mean? If it is ignored, my program 
using it compiled and run well. If the dependencies are not right, how 
can I fix it? I installed this by cabal. It reports nothing wrong and 
cannot check if all packages dependencies are OK.
4. When `cabal upgrade`, I do not think it knows what it is doing. There 
were many times that I cannot upgrade because I should manually 
reinstall some packages to make it work (Some guy say that this is 
because ghc cannot know the difference between two lib files with the 
same name). And, cabal does not upgrade all packages, I do not know why.
5. Sometimes when I upgrade some libraries, ghc failed to compile, 
because ld failed to find the new libraries. (Which proves that ghc 
cannot deal with binary files right). I need to recompile this, and 
recompile that, MAYBE it would be resolved.

Everyday, I spend a few hours on compiling. Does it really need to be so 
terrible? With erlang or ruby, I never spend more time debugging as 
haskell's feature says but less time on how to run my code.
