Well, I guess this isn't a random problem then. I had this in one of
the Linux boxes but the first thing I tried to solve it worked so
dismissed it as something not so important. Now dons had this problem
as well.

The solution: compile Hipmunk with --enable-split-objs .

Now, why that happens is something I don't know. Why split-objs helps
I don't know either. On the other Linux box and on the Windows one it
worked flawless without --enable-split-objs. Some GHC hacker around to
shed some light, please?
