sounds to me as if i'm using a more up-to-date tl than you are.  (note i
take my updates over nfs from the ctan server in the next corridor.)

looking at your offending package, i see

$ ls -l `kpsewhich puenc.def`
-rw-r--r--. 1 rf10 rf10 122261 2012-08-13 23:37 /local/texlive/2012/texmf-dist/tex/latex/hyperref/puenc.def

i.e., the package was installed yesterday, and would have appeared for
the first time in this morning's mirror.  are you *sure* you have an up
to date texlive?

the null document you previously posted.  i've now added some text in
the document body, but it plainly has no relevance

in an ideal world.  very few do (you wouldn't want many of them -- for
example, the latex tests are of the same order of size as latex itself).

in the real world, with software being developed by people in their
spare time, your "should" is one of those inaccessible pies, floating in
the sky, that no-one can get at.

but *everyone* knows that there are packages that can't coexist --
several (ones doing the same job in different ways) you wouldn't even
_want_ to coexist.

i agree with myself.

you've not even mentioned when you last updated, nor which repository
you were updating from.  (have you tried updating since you first
observed the effect, even?)
