Compiling dbus 0.21 errors

Kernel 2.6.5
Slackware 9.1
Python -V: 2.3.1
Pyrex: 0.9.1.1

I intend to use this in order to compile Rox-Session.

I tried CVS-ing the latest 5/2/04 and received the following.

Making all in mono
make[2]: Entering directory `/mnt/src/rox/dbus/dbus/mono'
mcs  --unsafe --target exe -L . -r dbus-sharp.dll -r gtk-sharp.dll -o
test-dbus-sharp.exe Test.cs
error CS0006: Cannot find assembly `gtk-sharp.dll'
Log:

make[1]: *** [all-recursive] Error 1

I tried to make gtk-sharp.dll directly, but there was no rule.
----------------
I downloaded the 0.21 tarball and received the following error:

In both cases, I used the default ./configure switches but added
--sysconfdir=/etc.

Thanks for any suggestions.
