You need a later version of libxml2 (or at least, a different one as possibly an older one would also work). I met this on Windows -- 2.6.23 is old (more than 2 years), and I believe 2.6.28, 2.6.30 and 2.6.31 work.
The Omegahat lists have been defunct for a while, AFAIK. I'd have used R-devel for this one ('discussion unintelligible to non-programmers'). Although not relevant here, there is a general principle that questions about the R-devel version of R should go to R-devel.

That one is lacking all the bug fixes in 2.6.1 and 2.6.2, as well as lots of nice features. > locale: > LC_CTYPE=en_US.iso885915;LC_NUMERIC=C;LC_TIME=en_US.iso885915;LC_COLLATE=en_US.iso885915;LC_MONETARY=en_US.iso885915;LC_MESSAGES=en_US.iso885915;LC_PAPER=en_US.iso885915;LC_NAME=C;LC_ADDRESS=C;LC_TELEPHONE=C;LC_MEASUREMENT=en_US.iso885915;LC_IDENTIFICATION=C > > attached base packages: > [1] stats graphics grDevices utils datasets methods base > > loaded via a namespace (and not attached): > [1] tcltk_2.7.0 tools_2.7.0 > > $ xml2-config --version > 2.6.23 -- Brian D.
