Unicode Prerequeites for dia-0.90 ?

["Frederick C. Druseikis" <fdruseikis sc rr com>]

Hello,

I've been trying to build dia-0.90 on my Red Hat 7.0 system (ximian 
desktop, up to date).
I'm receive in the following compilation errors that seem to be related 
to the libunicode version.
The following is output from make >err.out 2>&1

Can you tell me what unicode prerequsites I need.
I currently have:

libunicode-0.4.gnome-ximian.4.i386
libunicode-devel-0.4.gnome-ximian.4.i386

TIA
