setup : request

[Marco Atzeri]

Achim,
as you are playing with setup,
can you add a switch that allow to commute between:

old     behaviour : current or test is default installed
current behaviour : if installed is higher than current do nothing

The new behaviour is usually fine, but going back and forth
between all new perl test stuff is a pain when I need to remove
the 5.22 stuff.

I have no enough disk space to install 4 versions
x86 vs X86_64 + perl 5.14 vs 5.22

  ;-)

Regards
Marco
