Yes, it's almost certainly just the search path ordering. The problem  
is to get GHC to use the correct ordering. I've tried exporting


so that /usr/lib comes first. This doesn't seem to help. And it  
certainly is true that in some cases you want to prefer the MacPorts  
version, and in some cases you want to prefer the system version.

Do we need some more flexible options to GHC, giving users more  
control on the ordering of libraries on the linker command line?
