Maybe ... but we switched to Meson in between, so the patch needs to be 
rewritten to use meson.build instead, I think. Also it seems like version 
1.9 is not available in all distros yet, so someone needs to do an 
assessment whether the distros that use an older version of libgrypt provide 
a .pc file or not...
