[acroread7] Cannot find or create the font 'Arial'

[T. H. Lin]

FreeBSD 6.0-RELEASE #2
ports tree up-to-date

Recently I do the portupgrade,
and suddenly when I excute acroread7 to view some pdf documents(in german),
I got the error message:
    Cannot find or create the font 'Arial', Some characters may not display
or print correctly.

then I can read any character in the document.

but other documents are ok.


is the problem about fontconfig?
