"make update" is dangerous, basically.  useful, but dangerous...
   

oops, meant to add this:


one thing i do to avoid potential lossage is to use "pkg_tarup" (see
pkgsrc/pkgtools) on all the packages i see related to the one that
i wanted to upgrade, including dependancies, etc., of all the packages
this package depends on.  that way i have a binary package of the
things i need should i need to update stuff.


another related trick is to pkg_tarup the packages that also depend
on this packages depends, pkg_delete them, update, and pkg_add the
other packages back - this should work in nearly all cases (ones that
won't are when, eg, a shared library major is bumped.)


all these technique's are my own and are probably not well endorsed
by the pkgsrc team :-)
