"I found a duplicate definition for symbol: __x86.get_pc_thunk.bx" in package network

hi, i get this panic! using hint to interpret code which uses the network package (on 32bit ubuntu):

GHC runtime linker: fatal error: I found a duplicate definition for symbol
   __i686.get_pc_thunk.bx
whilst processing object file
   /home/mechgen/get_pc_thunk.bx/.cabal-sandbox/lib/i386-linux-ghc-7.10.2/network-2.6.2.1-F6mK9sCIw3M5SbZMt2lUQE/libHSnetwork-2.6.2.1-F6mK9sCIw3M5SbZMt2lUQE.a
This could be caused by:
   * Loading two different object files which export the same symbol
   * Specifying the same object file twice on the GHCi command line
   * An incorrect `package.conf' entry, causing some object to be
     loaded twice.
Left (GhcException "panic! (the 'impossible' happened)\n  (GHC version 7.10.2 for i386-unknown-linux):\n\tloadArchive \"/home/mechgen/get_pc_thunk.bx/.cabal-sandbox/lib/i386-linux-ghc-7.10.2/network-2.6.2.1-F6mK9sCIw3M5SbZMt2lUQE/libHSnetwork-2.6.2.1-F6mK9sCIw3M5SbZMt2lUQE.a\": failed\n\nPlease report this as a GHC bug:  http://www.haskell.org/ghc/reportabug\n")

the problem also arises when the interpreted module imports a module which imports network, so it doesn't have to import network directly.

also "it worked before". i can't really remember the previous working versions, but it must have been something like ghc 7.6.3 and haskell-platform 2013.2.0.0.

the related ticket mentioned building without -fPIC, but i can't find it in network's cabal file.
