Re: Question about SCons support of python 3 .6 and 3.7

Mats and Bill, thank you for help.

I currently solved test problems with Docbook, Clang and Java.

Docbook: 
There is entire "/src" directory previously was removed
from pre-build scons package within build sandbox env.
Now removing of files is more careful. It's spesific for gentoo
as source-based dist and it's build env.

Clang: 
The gentoo installation paths of clang are "   /usr/lib/llvm/*/bin".
So the problem is solved by creation of symlinks for clang and clang++
in /usr/bin or by passing additional paths to SCons env.

Java:
The problem of searching of apropreate include directory
was solved by patching posix.py script to add gentoo
java-jdk installation paths of packages "oracle-jdk-bin",
"openjdk-bin" and "openjdk":

I tested it only for package "oracle-jdk-bin-8.202".
The early failed Java test now is passed.
