    331. Every time I try to {{{cabal install}}} GenI, it keeps trying to build wxcore (and fails!) 
    4  * '''Solution''': {{{cabal install wx --configure-opt="--user --enable-split-objs --hcprof}}} (tested on 2009-02-12, Ubuntu Intrepid, wxWidgets 2.8, GHC 6.10.1) 
     4 * '''Solution''': 2009-02-14.  This is a tricky one.  For some reason cabal-install keeps trying to re-install wx  
     5 
     6 {{{cabal install wx --configure-opt="--user --enable-split-objs --hcprof}}} (tested on 2009-02-12, Ubuntu Intrepid, wxWidgets 2.8, GHC 6.10.1) 
     71. I get this error when I try to do {{{runhaskell Setup configure}}}: 
     8{{{ 
     9GHCi runtime linker: fatal error: I found a duplicate definition for symbol 
     10   waitForProcess 
     11whilst processing object file 
     12   /home/me/.cabal/lib/process-1.0.1.1/ghc-6.10.1/HSprocess-1.0.1.1.o 
     13This could be caused by: 
     14   * Loading two different object files which export the same symbol 
     15   * Specifying the same object file twice on the GHCi command line 
     16   * An incorrect `package.conf' entry, causing some object to be 
     17     loaded twice. 
     18GHCi cannot safely continue in this situation.  Exiting now.  Sorry. 
     19}}} 
     20 * '''Workaround''': I don't know the proper solution to this yet, but I found that it helps to {{{ghc --make Setup}}} and then call {{{./Setup}}} instead of runhaskell Setup
