Midi2Ly: "No module named fcntl"

[Dave LaDelfa]

Although some MIDI files convert correctly, this one
<http://wso.williams.edu/cpdl/sound/tall-vid.mid> produces an error in versions
of midi2ly through lilypond-2.7.37:

(this output from version 2.6.5)

C:\Program Files\LilyPond\usr\bin>midi2ly.py d:videte\tall-vid.mid
Traceback (most recent call last):

    for (dur, num, den) in allowed_tuplets:
SystemError: /var/fred/cvs/savannah/lilypond/installers/windows/mingw/src/python
-2.4.2-1/Objects/listobject.c:243: bad argument to internal function

In version lilypond-2.7.39, a different error is reported, and seems to be
irrespective of the MIDI file input (i.e. files that converted okay in previous
versions also fail in this manner):
