Thank you, Aditya, that was it.
I have added 'mpost' to 'shell_escape_commands' in texmf.conf file.
If it is possible, I would appreciate a warning that a shell command has
not been escaped.
I had no clue what might gone wrong.

And last but not least, do you think that metapost can be a security
threat? Because if not, I will write to TeXLive packagers to allow
escaping of the 'mpost' command.
