I have copied the git repository to the "oglplus" directory, opened it in terminal as a superuser. I typed "make". I saw the following error messages:
"Makefile:237: bld/devel/test04.d: No such file or directory"
and many others, that looks similarly.
After I tried to install the oglplus:"./install.sh". All, that happens after this, is single string "/usr/local", that prints to the terminal. I tried to invoke "install.sh" with the "---prefix /usr/local" parameter, but it changed nothing.
Here is the pastebin from my terminal: http://pastebin.com/hbZQhf1G
