I am having a problem rendering labels to my map. I am running mapserver from
ubuntu intrepid packages (none compiled). Kernel is 2.6.27-7-generic. Since
this is obviously a common function I must be doing something wrong in the
layer or something in the packages is not meshing. Everything works until I try
to do anything with TrueType fonts, but I am not sure why gdal would have
anything to do with this. When I try to add a label to a working layer (called
'clpoint'), the client gets a 500. Funny because the mapserver log reports lots
of stuff like this for the layer (but no error):

but syslog reports a bunch of these:

--Things I have checked
*The font.list is present and seems to be read (fails with a clearer error when
I reference a fake font.).
*The font file is a valid true type font and has all permissions. Tried
different fonts.
*The shape file and the dbf file are readable by other tools and CLPTLABEL in
the dbf file has the data I want.
Can someone please tell me where I am going wrong (and thank you)? Sorry for
the long post.
