That looked like a plausible explication, but is not the culprit here. I 
used Gabor's divide and conquer
strategy,  and found that by eliminating some files from the data  
subdirectory the error disappears and the
build completes. all of this files involves  SPSS .sav   files read with 
read.spss from package foreign
(I have latest version installed), and thereafter some data 
transformations.

However, moving the inflicted files to new test data only packages, they 
build without problems!

And, there is still left in my data subdirectory some SPSS .sav files 
which not makes problems.

Any ideas?
