OK, I'm redoing many many things due to the holes in my includes that 
occurred when I tried a 'make update' of a package (note to self- never 
again!!).  I suspect it will be a while before I find everything that 
got hit.

I'm getting some things, like this:

[...]
gmake[2]: Leaving directory 
`/usr/pkgsrc/textproc/libxml2/work/libxml2-2.6.13/example'
gmake[1]: Leaving directory 
`/usr/pkgsrc/textproc/libxml2/work/libxml2-2.6.13'
=> Unwrapping files-to-be-installed.
===> Installing for libxml2-2.6.13nb1
===> libxml2-2.6.13nb1 is already installed - perhaps an older version?
*** If so, you may use either of:
***  - "pkg_delete libxml2-2.6.13nb1" and "/usr/bin/make reinstall" to 
upgrade properly
***  - "/usr/bin/make update" to rebuild the package and all of its 
dependencies
***  - "/usr/bin/make replace" to replace only the package without 
re-linking
***    dependencies, risking various problems.
*** Error code 1
Stop.


What's up with that?  The versions are the same; usually it seems the 
script will just leave the installed part alone and go on to the next 
component.  But not here...

Forcing a delete (despite dependencies) and make reinstall worked here. 
  But I think it's things like this that killed the "automagic" rebuild 
of everything attempted by the 'make update' I'd tried a couple days 
ago.  I'm glad I had time today to keep at this.

Thanks for thoughts,

Brian
