dselect: improper dependancy resolution behavior?

["Gladimir" <listmgr@san.rr.com>]

I am hand selecting my packages, but I am having a problem with libncurses4
and libncurses5.  Until I know more about this, I suppose it won't harm
anything to just install both versions.  However, if I try to remove
libncurses4, the dependancy resolution also forces the removal of nvi.

It is my understanding the nvi is the linux version of vi, which I prefer to
use above any other editor.  Will nvi work with libncurses5?  If so, will it
hurt anything to 'manually' force the removal of libncurses4 in the future?

dselect - main package listing
## the following packages are installed and marked for install:

 *** Req base  libncurses5 5.0-6.0pota
 *** Req base  ncurses-base 5.0-6.0pota
 *** Req base  ncurses-bin 5.0-6.0pota

## the following packages are not installed, but marked for install:
  n* Imp oldlibs  libncurses4 4.2-9

  n* Std admin  ncurses-term 5.0-6.0pota

Thanks in advance for your help.
