[Haskell-cafe] Build dependency problem with bytestring.

[Jon Strait]

Hi all,

I'm upgrading HAppS from my 0.9.2 to the current 0.9.2.1 in Hackage.  
Some HAppS components have built and installed (IxSet and Util).  
Halfway through the HAppS-State build, the GHC runtime linker gives a 
fatal error on finding a duplicate definition for symbol fps_minimum 
while loading bytestring 0.9.0.4 after having already loaded bytestring 
0.9.0.1.  From trial and error, I'm guessing that HAppS-State needs 
0.9.0.1 but one of its build dependencies was built with 0.9.0.4.   
Using GHC 6.8.2 Linux here.

Any suggestions on how best to currently approach this situation?

Thanks,
Jon
