.dwg file viewer

To open a .dwg file,
was trying to compile lx-viewer
but then stucked at ad2.a and ad3.a, OpenDWG library files..

And found below link,
http://www.fsf.org/campaigns/priority.html#opendwgreplacement

Now what? ..

Wikipedia says..

There are no open source viewers for DWG files since the licensing of the libraries needed by lx-viewer^[41] now restricts their use to members of the Open Design Alliance.

sigh..
