upgrading in same installation dir?

[Dan Muresan]

Hi,

suppose I have an octave version (from the hg stable branch) installed
in /opt/octave. -forge packages have been installed there too (with
pkg -global -forge).

Then I do an update (hg pull -u). Is it then safe to "make install" to
the same directory (which I guess overwrites the old installation)? Or
do I need to clean the installation directory, "make install" and then
re-install the -forge packages?


Thanks,
Dan
