This was the effect of an incompatibility between the doc package and natbib. Since the former seemed to be unused in the document, I removed it form the git version and things should now be ok. (The funny thing is, the same package is used in gretl-mpi.tex too, but seems to do no harm. Go figure)

Also strange: on my texlive system there's no conflict between doc.sty and natbib, the citation in question works fine. I was going to say, I have no idea why the "doc" package is loaded by any gretl-related latex file -- since it appears to be all about documentation of TeX code itself -- but then I found a reason why it's included by pkgbook.tex: it defines \BibTeX, which is wanted there. Elsewhere it shouldn't be needed.
