1.5

It's *sortof* true.  Current behavior is much better than before.  The 
old behavior messed up even during the normal build phase IIRC -- which 
necessary messed up 'make install' (no DESTDIR) too.

Plus, if you DIDN'T have the 'old' version installed, then 'make install 
DESTDIR' would fail completely during relink -- because it'd try to link 
exclusively against (e.g.) /usr/lib and NOT <inst>/usr/lib at all.

Now, 'make' and 'make install' Do The Right Thing in 1.5.  Even 'make 
install DESTDIR' works when the old version (of the dependee library) is 
not installed.  The only problem is 'make install DESTDIR=....' with 
pre-existing installation of the old dependee lib.

That's an improvement, certainly -- but it ain't perfect.  Hopefully the 
test case will help in the future to work out this last remaining wrinkle.
