now what? getting "No driver is available! (PkgDB::DBError)" whenever trying to run any port* command

[Dan Finn]

I am trying to get the new version of firefox to build and I am having
a wonderful time doing it.  I was getting errors when building firefox
about :
Undefined symbol "FT_Get_BDF_Property" from libfontconfig

so I rebuilt freetype2, fontconfig and libXft in that order per
someones suggestion on this list.

Now when I tried to portupgrade firefox I got the following error:

../../../../dist/bin/xpidl -m typelib -w -I ../../../../dist/idl -I.
-o _xpidlgen/nsIBoxObject nsIBoxObject.idl
/libexec/ld-elf.so.1: Shared object "libIDL-2.so.0" not found

so I figured I would check to make sure I was running the latest
version of libIDL and all of a sudden I am getting these errors:

[ root @ stewie : ~] : portversion -v libIDL

great!  what's going on here?

Thanks
