Hello, I ran into some dependency issues with cabal/ghc and could not find any solution on the internet. ghc-pkg check returns nothing, I suppose this is a good thing. But ghc -v returns: ----------------- Glasgow Haskell Compiler, Version 7.4.1, stage 2 booted by GHC version 7.4.1 Using binary package database: /usr/lib/ghc/package.conf.d/package.cache Using binary package database: /home/ming/.ghc/x86_64-linux-7.4.1/package.conf.d/package.cache package blaze-svg-0.3.3.0-50a04482f1f501336d4772805c49480c is unusable due to missing or recursive dependencies: mtl-2.1.1-801101765c9185fec3b8dbd5355f5550 package cairo-0.12.3.1-b5380fec59ee27dbcea4803a68e97987 is unusable due to missing or recursive dependencies: mtl-2.1.1-801101765c9185fec3b8dbd5355f5550 package gio-0.12.3-d4fa99730a97194e714a9725fe2ce6eb is unusable due to missing or recursive dependencies: mtl-2.1.1-801101765c9185fec3b8dbd5355f5550 package gtk-0.12.3.1-b4f922f5295267731eb0ea058e8ec63b is unusable due to missing or recursive dependencies: cairo-0.12.3.1-b5380fec59ee27dbcea4803a68e97987 gio-0.12.3-d4fa99730a97194e714a9725fe2ce6eb mtl-2.1.1-801101765c9185fec3b8dbd5355f5550 pango-0.12.3-86ce88701ca575a64c78e01efb6107e7 package httpd-shed-0.4-4efc4f08c1e731625a137a46b01eaa91 is unusable due to missing or recursive dependencies: network-2.3.1.0-acf1a3e75cbe81f030e6d7af508f064a package network-2.3.1.0-acf1a3e75cbe81f030e6d7af508f064a is unusable due to missing or recursive dependencies: parsec-3.1.3-0cb02763c2a282c8ea5c85882f9bf27d package pango-0.12.3-86ce88701ca575a64c78e01efb6107e7 is unusable due to missing or recursive dependencies: cairo-0.12.3.1-b5380fec59ee27dbcea4803a68e97987 mtl-2.1.1-801101765c9185fec3b8dbd5355f5550 package parsec-3.1.3-0cb02763c2a282c8ea5c85882f9bf27d is unusable due to missing or recursive dependencies: mtl-2.1.1-801101765c9185fec3b8dbd5355f5550 package soegtk-0.12.1-da31ebdf63cd5bad394b6fa20d55647e is unusable due to missing or recursive dependencies: cairo-0.12.3.1-b5380fec59ee27dbcea4803a68e97987 gtk-0.12.3.1-b4f922f5295267731eb0ea058e8ec63b wired-in package ghc-prim mapped to ghc-prim-0.2.0.0-c2ff696e5b8ec4d4b2bc2e42085fe471 wired-in package integer-gmp mapped to integer-gmp-0.4.0.0-3cccac07aef8e27023f605c1f45bdf74 wired-in package base mapped to base-4.5.0.0-40b99d05fae6a4eea95ea69e6e0c9702 wired-in package rts mapped to builtin_rts wired-in package template-haskell mapped to template-haskell-2.7.0.0-8c8cd20e21666657195efabced685fe1 wired-in package dph-seq not found. wired-in package dph-par not found.

I already reinstalled GHC completely but it didn't change anything. Is there anything I can do? Thank you in advance.
