This is a link issue with multimedia on Lion. It seems that Quicktime is a
32 bit library only. You can ignore this.

I need to check, but this looks as though you have a version of wxc which
is incompatible with the wxcore you have. This is almost probably my fault
(incorrect dependencies), and nothing to do with you - the install steps
you have taken look correct to me.

I will check whether I see the same problem on a clean install of
wxHaskell, and upload a new version if needed.

These steps look correct to me.

This is the C++ version of the warning that Quicktime is a 32 bit
framework, and cannot be linked to a  64 bit binary. Again, you can ignore
this (it needs to be fixed in wxWidgets).
