Hello, I just updated mupdf to the latest version 1.8 and streamlined the package recipe at the same occasion. As a result, the binary is now called "mupdf-x11" instead of "mupdf"; previously the makefile was patched to change the name. As we usually follow upstream (for instance, we keep the "soffice" binary instead of calling it "libreoffice"), I think this is in line with our policy and did not port that part of the patch.
