[gmx-users] upgrade version - "make distclean"?

[Low Soo Mei]

Hi,

I would like to upgrade from version 3.3.2 to 3.3.3 on my local 
computer, non-parallel for both.  Can I confirm that I should

1)  cd to the gromacs-3.3.2 directory
2) type "make distclean"
3) then delete the entire gromacs-3.3.2 directory

, to clean 3.3.2 off my computer entirely?

I am still optimizing my MD simulations and would like to attribute 
simulation errors to only my simulation parameters and not to some 
installation/upgrade problem.  No previous advice on upgrading was 
available from Google or the Gromacs wiki or mailing lists.

Thanks in advance.

Cheers,
Soo Mei
