[plt-scheme] OpenGL support in plt scheme v205

The release notes say that v205 has "Better OpenGL support; download the
`sgl' addon for a higher-level". 

The sgl download page says that sgl will be incorporated in v205 and
that the current version is obsolte. I tried to go a get the sgl
collection using CVS. I did this copied it into the collections folder
and ran plt-setup. The setup program gacked when it came to this
collection. Is there something I'm missing here? Is the plan to make sgl
part of the standard distriubtion?
