I have the network package already installed. When I try to reinstall it (for use with cabal-dev, for example), it won’t compile. If I cabal unpack network and then try to build that, I get the output below. I am guessing that this broke because I upgraded an Ubuntu dependency. I upgraded to Ubuntu 11.04 in hopes that it would help; it didn’t. Also installed libghc6-network-dev in case that would make things link correctly; it didn’t. I am on ghc-7.0.2, and just tried ghc-7.0.3 also. Currently trying installing the latest haskell platform from source… Any help appreciated- this is completely killing my haskell hacking!

Here is my gcc version:
/usr/bin/gcc --version gcc (Ubuntu/Linaro 4.5.2-8ubuntu4) 4.5.2
I upgraded to ghc 7.0.3 and then installed the 7.0.3 haskell platform from source, and now everything is working. Not that I understand why 🙂
