I have juste re-build the last development release of Wine (http://www.winehq.org) Release for OpenSolaris - 2008.05 with openGL Libs. So you can run OpenGL Window Programs like Google Earth in your OpenSolaris desktop.
Last Wine Package Files is available at http://mpkgopensolaris.sourceforge.net/wine/Wine-1.1.2-solaris-5.11-i86pc.pkg.bz2
Just download the file here, and install it with following commands:
# bunzip2 Wine-1.1.2-solaris-5.11-i86pc.pkg.bz2
# pkgadd -d ./Wine-1.1.2-solaris-5.11-i86pc.pkg
And Try to install Windows Google Earth by downloading Windows GoogleEarthWin.exe file in your Desktop, and then install Google Earth with:
[1] /usr/local/wine/bin/wine --version
wine-1.1.2
[2] /usr/local/wine/bin/wine /home/jblanche/Desktop/GoogleEarthWin.exe
Have Fun with Wine and OpenSolaris
