[svn-r3200] Purpose:
    Bug fix
Description:
    install method was cached as 'cp -r'.  It did not work
    in --srcdir option as the configure set the method to ../cp -r.
Solution:
    Removed the cached entry.  Let it look for install or use install-sh.
Platforms tested:
    LLNL Blue (found and used /usr/local/gnu/bin/install).
