The following patch to happstack works for me:
This worked for us as well. Thanks, Gregory.
Do you know if it's possible to permanently patch happstack-server?
I'm guessing the TH in the patch is used to support multiple versions
of the network package. Can we just change the minimum supported
version?
There's been an open ticket for months; personally I think this is a job
for the C preprocessor, but nobody's written a patch yet. I'm not sure
but I think IPv6 template Haskell stuff is there not to support old
versions of network, but to support platforms where IPv6 may not be
available.
