Dear bear users,

I just uploaded the installation script (preinst.r, v6.1) of bear to Sourceforge. The update solves the issues due to the retired RGtk2 & cairoDevice, as well as previous gWidgets & gWidgetsRGtk2. Also the issue of Graphics API version mismatch/bump in Debian for R 4.1.x. Now building from archived sources for these four retired packages is not a problem for Linux (Debian/Ubuntu) and macOS. However, it is a really big problem for Windows now. That is because the user needs to install and set up a GTK development program first to build RGtk2 from its source. We used to install RGtk2 using its "binary" directly downloaded from CRAN. It's the good old days. So far, I still cannot figure out how to successfully do that. Therefore, for Windows OS, the best way to install RGtk2 & cairoDevice is from their binaries (*.zip). Fortunately, we still can find their binaries from cran.microsoft.com/snapshot. Thanks to Microsoft this time, as well as the Google master. Don't know how long this Microsoft website can remain valid. Of course, I will try to figure out how to build RGtk2 & cairoDevice from their sources for Windows OS as possible as I can. That's it.
