Other cde 2.2.4 compile error

Hello I have just tried to compile cde 2.2.4 and have got the following error:

missing file pkg-message.in previously I have successfully compiled and installed cde 2.2.3 without any build errors. Any Ideas how to fix this?
Sorry I am very new to this, could you tell me how to download cde via the git repo? Thanks Nedry
Something like this should work:
git clone git://github.com/MikaelUrankar/cde.git cde-port
That will place the clone in a directory called cde-port

I see an error though during the make:
make[5]: don't know how to make ./src/cmd/ksh93/main.o. Stop
