viewcvs should require python-subversion

[acutler]

Binary package hint: viewcvs

viewcvs requires python-subversion for correct operation.

If this is not installed then it will fail with "ImportError: No module named svn"

(although it seems python-subversion is sufficient, python2.4-subversion may be required also)

python-subversion (which depends on python2.4-subversion) is a recommends. If you use viewcvs with a CVS install, you do not need this module. It looks like logical to me, even if it is always a subject than can be discussed...

[acutler (acutler)]

True however, ViewCVS has now been renamed ViewVC which nicely reflects that it is no longer just for CVS. So going forward is there a way to install the CVS or Subversion components depending on whether svn or cvs is installed? Or perhaps ask the user?

I think in any case I should file a bug report with upstream to see if we can get that error message cleaned up. (It caused me far more grief than necessary for a simple failed dependency)

We are not going to divert from Debian on this, suggests is sufficient for python-subversion.
