Description

Cygwin can't load shared libraries via symlinks. Therefore, we have to actually copy libcsage.so/csage.dll over to $SAGE_LOCAL/lib/. Note that currently the "install" target in SConstruct does nothing.

Unfortunately, after applying this, libcsage just doesn't build anymore.

However, Mike says there is a Python spkg that may fix this...
