Hi tex-live at tug.org,

(the author of natbib is also CC'd)

I am working on packaging tl-2009 and have hit a problem with natbib.








        author = "Some Person",
        organisation = "{LLVM Web Team}",
        title = "{The Low Level Virtual Machine Compiler Infrastructure Web Page}",
        url = "http://llvm.cs.uiuc.edu/",
        year = "2009",
        note = "Accessed on 11th February 2009" 


snippet of output (pdflatex):
Document Class: article 2007/10/19 v1.4h Standard LaTeX document class
(/usr/local/share/texmf-dist/tex/latex/natbib/natbib.sty) (./test.aux

! Package natbib Error: Bibliography not compatible with author-year

(natbib)                Press <return> to continue in numerical citation

See the natbib package documentation for explanation.
Type  H <return>  for immediate help.
l.7 ...mmand\NAT at force@numbers{}\NAT at force@numbers

The reference in question was one take from my dissertation which used
to work well in TL-2008. I even added the author "Some Person", just to
check it didn't require an author field.

This error is reported on the internet here:

As they suggested, I tried \listfiles:

 *File List*
 article.cls    2007/10/19 v1.4h Standard LaTeX document class
  size10.clo    2007/10/19 v1.4h Standard LaTeX file (size option)
  natbib.sty    2009/07/16 8.31 (PWD, AO)

I am using the 20091009 distributors tarball on OpenBSD.

It seems that this is the most recent version of natbib.

As a test, I put the texlive 2008 natbib.sty and plainnat.bst files in
my ~/texmf and updated my lsr's. Everything worked as expected.

Looks like the new version of natbib is broken.

Best Regards
Edd Barrett
