#1 Missing GPL version 2 license

[Michael L. Heuer]

Hello,

I could not find the GPL version 2 license in the source download.

Per How to use GNU licenses for your own software, GPL2 projects should include a copy of the license itself (in a file called COPYING, by convention) and a license notice in the header of every source file.
