It appears the support for texlive packages on some hosts is variable. This patch lets us add missing packages to our source tree so a PDF can be built on those hosts. The quality of the PDFs created may vary as some short cuts may have been take. For example lato is a font and only the sty file as been added and not the actual font which means it's use will default to another font.
