problems with lilypond-snapshot 2.3.20

[Paul Scott]

I get this from a file which worked yesterday with 2.3.19:

address@hidden:~/music/catalina$ lilypond-snapshot bf15r1.ly
dirname: too few arguments
Try `dirname --help' for more information.

Now processing `bf15r1.ly'
Parsing...
Interpreting music... error: can't find `ecrm10.pfa'
Install the ec-mftraced package from 
http://lilypond.org/download/fonts/. Aborting
