Apologies if my message appeared snarky, but I wasn't smart enough to see the 
big picture before I hit send.

I think there are three cases:
  build for testing/development
  install the current stuff
  build for packaging

"scons" does the first.
"scons install" does the the second.  It copies over the current stuff and 
then uses chrpath to fixup the RPATH stuff to point to where it will (or did) 
install the libraries.

I don't know what to type to get the third case.  I want the local 
executables and libraries to have the right RPATH stuff so I can copy them 
over into the the packaging file (rpm, whatever...)

Perhaps things should be stored in a staging directory so the executables in 
the local directory will continue to work.  (That sounds like a good policy.)

----------

There is an additional tangle if you specify a DESTDIR.

scons is setup with a default of /usr/local  That needs an RPATH (or 
something?) to get the libraries from /usr/local/lib rather than /usr/lib

Miroslav wants to install in /usr which doesn't need any RPATH.  The current 
scons install leaves a RPATH of /usr/lib rather than deleting it.

----------

The current scons also mangles the RPATH in the local executables if you 
specify a DESTDIR.  I don't think that makes sense.  When it's installing 
things, it copies and then chrpaths the copied vesion.  Why should it change 
(break?) the local stuff before the copy?
