Ditto.  Then it got real scary.

Actually, much worse than that.  Run this:
        strace -o tmp scons check

The look at the file: tmp.  You will think Halloween cam early.  I had
to sleep with the lights on last night.

I still can't figure out how to describe the horrors.

That is odd.  But maybe intentional so group 'user; can install there.

On Gentoo:

$ ls -ld /usr/local/bin
drwxr-xr-x 2 root root 4096 Oct  4 13:10 /usr/local/bin

The strace says something neither of us expected is happening:

unlink("/usr/local/bin/gegps")          = -1 EACCES (Permission denied)

Along with a large number of other scary things...

gegps actually has nothing directly to do the GE.  It just writes a
KML file.  Useful for many things other than GE.

No got look at the strace output.

I'm working on some SConstruct fixes for this.  I have always avoided
SConstruct.  Many problems in the same area.  Some stuff, like
check_compile(), do not look like they ever worked.  Then the new
problem that I made (python_versions).

And, something I noticed before, a lot of the check routines may
fail, but scons keeps on going..

I'm guessing a 3.18.1 next week....
