Dear R-Devel,

Note:  I posted a similar message to R-sig-debian yesterday because I 
assumed it was a Debian issue, received response that it it may be more 
appropriate for r-devel since it involves building from the svn version.

As of Oct 21, we are running into a build failure when trying to
compile the development version of R from the svn repository.  The 
problem still persists as of Revision:64096:

We are running:

./configure && make -j4 distclean && ./configure && make -j4

[lots of normal compile output not shown...]

building/updating vignettes for package 'utils' ...
processing 'Sweave.Rnw'
Error: running Sweave on vignette

failed with message:
<text>:1:1: unexpected '|'
1: |
Execution halted
make[1]: *** [vignettes-lattice] Error 1
make[1]: Leaving directory
make: *** [vignettes] Error 2

The same vignette compiles without error on the same machine using the
stable release version of R (which we also build from source with same 

Dirk reported yesterday that he was unable to reproduce the problem on 
r-devel svn "..Using Ubuntu 13.04, current"

Does anyone have suggestions on how I might debug this further to 
determine if this is an issue with Sweave, or something with our system 
configuration which would impact one build and not the other?  When I 
diff the files in utils I see quite a few changes to Sweave between the 
stable and devel branches, but I'm not sure how to interpret them.

thanks for your help,
