[petsc-dev] Undefined symbol in SLEPc dylib (Haskell bindings, OSX)

[Marco Zocca]

All the KSPConv* symbols are defined (`nm -u ...` shows the blank string):

$ nm ${PETSC_DIR}/${PETSC_ARCH}/lib/libpetsc.3.7.2.dylib | grep KSPConv

000000000110a652 T _KSPConvergedDefault
0000000001109703 T _KSPConvergedDefaultCreate
