This might a good time to remind everyone that every single program compiled by a standard GHC is linked against an LGPL library (the Gnu multi-precision integer library) - unless you take care first to build your own copy of the compiler against the integer-simple package instead of integer-gmp.  As far as I know, there are no ready-packaged binary installers for GHC that avoid this LGPL'd dependency.

Just saying.
