Hi, When I try to build my HaskellForMaths library (http://hackage.haskell.org/package/HaskellForMaths) using GHC6.10.4 on Mac OS X (Leopard), I get several "ld warning: atom sorting error" (see below). The same code built without problems under GHC6.10.3 on Windows. The code in question is using phantom types to parameterise type constructors. Should I be worried? (It's only a warning - I believe the build is fine.) ld warning: atom sorting error for _HaskellForMathszm0zi1zi8_MathziAlgebrazi CommutativeziMonomial_Grevlex_closure_tbl and _HaskellForMathszm0zi1zi8_MathziAlgebrazi CommutativeziMonomial_Lex_closure_tbl in dist/build/Math/Algebra/Commutative/Monomial.o ld warning: atom sorting error for _HaskellForMathszm0zi1zi8_MathziAlgebrazi CommutativeziMonomial_Glex_closure_tbl and _HaskellForMathszm0zi1zi8_MathziAlgebrazi CommutativeziMonomial_Grevlex_closure_tbl in dist/build/Math/Algebra/Commutative/Monomial.o ld warning: atom sorting error for _HaskellForMathszm0zi1zi8_MathziAlgebrazi CommutativeziMonomial_Elim_closure_tbl and _HaskellForMathszm0zi1zi8_MathziAlgebrazi CommutativeziMonomial_Glex_closure_tbl in dist/build/Math/Algebra/Commutative/Monomial.o ld warning: atom sorting error for _HaskellForMathszm0zi1zi8_MathziAlgebrazi CommutativeziMonomial_Grevlex_closure_tbl and _HaskellForMathszm0zi1zi8_MathziAlgebrazi CommutativeziMonomial_Lex_closure_tbl in dist/build/Math/Algebra/Commutative/Monomial.o ld warning: atom sorting error for _HaskellForMathszm0zi1zi8_MathziAlgebrazi CommutativeziMonomial_Glex_closure_tbl and _HaskellForMathszm0zi1zi8_MathziAlgebrazi CommutativeziMonomial_Grevlex_closure_tbl in dist/build/Math/Algebra/Commutative/Monomial.o ld warning: atom sorting error for _HaskellForMathszm0zi1zi8_MathziAlgebrazi CommutativeziMonomial_Elim_closure_tbl and _HaskellForMathszm0zi1zi8_MathziAlgebrazi CommutativeziMonomial_Glex_closure_tbl in dist/build/Math/Algebra/Commutative/Monomial.o
