Hi guys, I tried to install haskell-src-meta and got the error below. I checked all dependencies which are listed on the hackage page, they are all installed with the right version. Can anyone tell me what is the problem? Thanks a lot. jqc@ubuntu:~$ cabal install haskell-src-meta Resolving dependencies... Configuring haskell-src-meta-0.3...
