Building Ristretto.

[Jose Luis Pavón]

Hi! I'm trying to build the las Ristretto from git and I get the
following error...

image_viewer.c:32:10: fatal error: marshal.h: No such file or directory
 #include "marshal.h"
          ^~~~~~~~~~~
compilation terminated.
make[3]: *** [Makefile:614: ristretto-image_viewer.o] Error 1
make[3]: Leaving directory '/home/jolupa/Baixades/ristretto-0.10.0/src'
make[2]: *** [Makefile:472: all] Error 2

make[1]: Leaving directory '/home/jolupa/Baixades/ristretto-0.10.0'
make: *** [Makefile:449: all] Error 2

The problem didn't exist with the tarball in archive and build
correctly.
Any hint?
Thanks!
