Can't exec "dot": Ficheiro ou directoria inexistente at Build.PL line 14.

On Ubuntu, I also don't have "dot": 
$ dot --help
The program 'dot' is currently not installed. You can install it by ty
+ping:
sudo apt-get install graphviz
$

Not sure what the intent of Build.PL is, but if I wanted to install GraphViz then I would first install "dot".
I think that should enable installation of that module.

version.c:30:16: fatal error: db.h: Ficheiro ou directoria inexistente #include <db.h>

db.h is not being found - you can fix this by adding the location of db.h to the CPATH environment variable: 
export CPATH=/wherever/it/is:$CPATH

[download]
I think you'll subsequently find that the DB library is also unlocatable - which will result in unresolved symbols when you try to run the module (eg during 'make test' stage of the build).
That being so, I would try adding the location of the DB library's .so file to the LD_LIBRARY_PATH environment variable: 
export LD_LIBRARY_PATH=/wherever/it/is:$LD_LIBRARY_PATH

[download]
Or maybe you need to add the location of the static DB library (.a) to the LIBRARY_PATH environment variable.
I'm a little unsure as I've never managed to properly understand the way linking is effected on Linux - I just usually stuff around with things until I find something that works.
Maybe someone else can chime in here with some more definitive advice.

Cheers,
Rob
