[Cin] latest hacks

[Andrea paz]

Without being root the compilation stops after a few seconds because
it doesn't find the libzmpeg3 directory. As root the compilation goes
on more, but also fails. I enclose the cin5-root.log
Apologies for the Italian output; I tried using LC_ALL=C before to
exec "make", but it still uses Italian...
(NOTE: if it is possible, I would like to be able to continue
compiling without becoming root)
