Cannot construct uuid exec: "uuidgen": executable file not found in $PATH
A program should never assume that some other program is installed. It should mentioned in the README that some other packages are required.

mapago will not be platform independent if external programs are used (e.g. how to install uuidgen in windows? uuidgen.exe?
