Now also available in Gentoo Linux, along with the bundled lib 
protocol-buffers-descriptor and the tool hprotoc.

Get it from the haskell overlay
  * dev-haskell/protocol-buffers
  * dev-haskell/protocol-buffers-descriptor
  * dev-haskell/hprotoc

It's noticeable that we too were required the -fvia-C flag to build 
protocol-buffers package. I'm using GHC 6.8.3 on amd64. Without it, ghc 
died with the following error message:

/tmp/ghc20461_0/ghc20461_0.s: Assembler messages:

/tmp/ghc20461_0/ghc20461_0.s:6993:0:
      Error: too many memory references for `movzbl'

/tmp/ghc20461_0/ghc20461_0.s:6994:0:

/tmp/ghc20461_0/ghc20461_0.s:6995:0:
      Error: suffix or operands invalid for `or'

We also apply the following (tiny) patch to get hprotoc to compile:
