A little bit of detective work indicates that the vignette was building 
fine on all platforms until commit 7ed2a00e This commit added 2 things 
to the rgsepd.Rnw vignette: (1) a new biblio entry and (2) a \verb 
paragraph with reference to the new biblio entry.

Apparently, the new biblio entry is causing problems. It seems to 
trigger some bad interaction between knitr and biblatex that seems to be 
specific to the MacTeX version (mactex-20161009) that we use on our Mac 
builders. Remember that we're stuck with El Capitan on these builders so 
updating things there can be tricky.

Anyway, the problem goes away if you use natbib (used by hundreds of 
Bioconductor packages) instead of biblatex (only used by a handful of 
Bioconductor packages). That is, if you replace:




and move


to the line where you currently have


(get rid of the \printbibliography directive)

With this change, I can successfully 'R CMD build rgsepd' on merida2 
(didn't try on celaya2 though).

Hope this helps,
