Need help compiling ORBit 0.5.7

[poshea mini pair com]

I'm trying to compile the various components of Gnome, because
there's no distribution for Solaris 2.6.  I've got gtk, glib,
imlib, xpm, and DB compiled, but am having problems with ORBit.

This is the output I'm getting from make:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
/bin/sh ./libtool --mode=link /apps/gnutools/bin/gcc  -g -O2  -o tstidl  tstidl.o libIDL.la -L/home/poshea/bin/gnome/lib

Some background info: this is an Ultrasparc running Solaris 2.6, 
and since I'm in a corporate environment and don't have root
privileges, I'm using --prefix=/home/poshea/bin/gnome for 
everything.

Any help that will get Gnome running for me so I can ditch
Common Desktop Environment 1.2 will be very much appreciated.
