Hi Federico,

these errors are due to the fact that the tablature features (including 
the moderntab clef and the
definitions for a seven-string guitar) are not included in 2.13.3 - 
either you change your file to
six strings (by ommitting the \set TabStaff.stringTunings = ... line 
completely) and the
calligraphic tab clef, or you just ignore the messages, because lilypond 
compiles in either case.

This error comes from the missing definition for seven strings...

Sorry, this is a little bug in tablature.ly; please search the line 
where you can find

#(define (parenthesize-tab-note-head grob)

and change it to

#(define-public (parenthesize-tab-note-head grob)

Then (hopefully) everything will be ok.

Sorry for the inconvenience and thank you for testing!
