Comment (by bkomuves):
I managed to build binaries on 10.5 which work on 10.4, however the
solution was very hackish. In theory it is quite simple, but it needs
knowledge about the ghc build system (which I don't have).
What I did was the following: I recompiled the runtime system and the base
library with passing the appropriate flags to gcc and the linker. These
flags are listed on thread linked above. (I think the Unix library also
has to be rebuild, but my program did not depend on it; and maybe some
other fundamental libraries, but not many). After this, I have to pass the
same flags when building my program, and then it will work on both 10.4
and 10.5 (if I don't pass the flags, it will still work on 10.5).
The build system (this was with ghc 6.10.1, so I think that's the old
build system) had in fact some infrastructure in it for doing exactly
this, but it seems to be bitrotten, as it worked only for the runtime
system, iirc (or maybe I made some mistakes, as I didn't build a full
ghc). So I just patched manually various configure files and whatnot, very
brute-force, but it worked.
