No these are extras, not required to stitch panoramas with hugin.

PTStitcher: now largely superceded by nona/enblend.

PTOptimizer: source is now part of the libpano12 package.

PTMorpher: merge two images by interpolating between control-points.   
This is a fairly standard image morphing tool.

PTAverage: merge multiple images by simple averaging of pixel 
values.  This can be replicated in a photo editor with some effort.

PTStripe: assembles multiple pictures taken around an object into a 
long strip suitable for viewing in an object viewer (such as the 
ptviewer applet) - This is simple image-appending easily replicated 
by imagemagick.

PTStereo: assembles 3d texture-mapped models of scenes based on 
multiple source photos - I would *love* to have a Free software 
version of this to play with.

PTInterpolate: I think this takes the output from PTStereo and 
renders intermediate viewpoints.

There isn't one in the panorama-tools-nonfree package (though there 
is a PTOptimizer symlink required to get the java tools working.  Is 
that what you are seeing?).

ptpicker is a front-end analogous to hugin.  I believe that the only 
advantage it has is that it allows you to pick control-points in 
sets-of-three (necessary to drive the PTStereo tool).

pteditor is a viewer that allows you to extract parts of a panorama  
as 'snapshots'.  You can edit these snapshots in the gimp and 
reinsert them seamlessly - It would be nice if panoglview acquired 
this functionality.

ptcrypt is a tool for scrambling jpeg images in a way intended to 
allow people to post panoramas on web-sites without making the raw 
image available - I seem to remember the encryption scheme was 
cracked within hours of release.

Unfortunately, the java tools expect to write files in your working 
directory, so the way to get them working is this kind of nastiness:

   chown username /usr/share/panorama-tools

No, although they are licensed under the GPL, they have no available 
sourcecode.
