midi2ly error message

[Guido Milanese]

I apologize for asking a question that seems to be almost a FAQ, but 
checking with Google I found only answers useful for the Windows 
version, while I am using lilypond on a Linux Mandrake system.

The question regards an error message of midi2ly:

  File "/usr//bin/midi2ly", line 43, in ?
    import midi
ImportError: No module named midi

I read how to solve it in Windows, but what about Linux?
Which file is the script looking for? And where can I download the 
file from?
The version of lilypond I am running is 1.7.14. 

Many thanks!
