32 to 64 bit problem

[Luca Ciciriello]

Hi All.
I think this is a not new question, but probably a missed it.

On my MacOS X 10.5 (32 bit) I use GHC 6.10.4 (installed by Mac package GHC-6.10.4-i386.pkg) to build some halkell programs and all is fine. Yesterday I've updated the system to MacOS X 10.6 (64 bit) and now when I try to build the same programs I get the errors:

/var/folders/vr/vrW2wwvtFKScalkhVEWujE+++TI/-Tmp-/ghc1613_0/ghc1613_0.s:1167:0:
    32-bit absolute addressing is not supported for x86-64

/var/folders/vr/vrW2wwvtFKScalkhVEWujE+++TI/-Tmp-/ghc1613_0/ghc1613_0.s:1167:0:

/var/folders/vr/vrW2wwvtFKScalkhVEWujE+++TI/-Tmp-/ghc1613_0/ghc1613_0.s:1170:0:
    32-bit absolute addressing is not supported for x86-64

Is there any solution to continue to use the installed GHC on the new 64 bit system? 

Thanks in advance for any answer.

Luca
