The first problem are the access rights.  Shared libs must have the
execute bits set.  chmod +x mysql.so will help.

The second problem is that this shared lib has been created for the
native win32 version of ruby, not for the Cygwin version.  It *might*
work together, but it's neither guaranteed, nor supported.

The third problem is that right now there's no Cygwin ruby-gems package
in the cygwin net distribution.  Volunteers welcome.
