No, the LGPL doesn't mandate source redistribution when you redistribute
a binary that is dynamically linked to a LGPL-licensed library.  If GHC
did support dynamically linking programs, it wouldn't be an issue, but
GHC only supports that on OS X.  

I was wondering something similar - is it really easier to replace the
functionality and speed of GMP than to extend GHC's dynamic library
support to other platforms?
