fontconfig problem with 2.10 on mac os x 10.4.11

[Peter Van Kranenburg]

After upgrading mac os x from 10.4.10 to 10.4.11, lilypond 2.10 gives the 
following error message:

Preprocessing graphical objects...No fonts found; this probably means that the 
fontconfig
library is not correctly configured. You may need to
edit the fonts.conf configuration file. More information
about fontconfig can be found in the fontconfig(3) manual
page and on http://fontconfig.org

It worked before. Lilypond 2.8 still works.

Does someone know how to repair this?

Thanks in advance,
Peter van Kranenburg
