[MonoDevelop] Problems compiling gtk-sharp-2.4.2

[almost]

Hello!!

I'd really like to get monodevelop running on my Slackware 11 distro, but 
I'm having a hard time at the moment.

During the compilation of gtk-sharp-2.4.2 I receive this message :

-------------------------------------------------
Making all in gnomevfs
make[3]: Entering directory 
`/usr/local/etc/frame/gtk-sharp-2.4.2/sample/gnomevfs'
make[3]: *** No rule to make target `../../gnomevfs/gnome-vfs-sharp.dll', 
needed by `TestXfer.exe'.  Stop.
make[3]: Leaving directory 
`/usr/local/etc/frame/gtk-sharp-2.4.2/sample/gnomevfs'
make[2]: *** [all-recursive] Error 1
make[2]: Leaving directory `/usr/local/etc/frame/gtk-sharp-2.4.2/sample'
make[1]: *** [all-recursive] Error 1
make[1]: Leaving directory `/usr/local/etc/frame/gtk-sharp-2.4.2'
make: *** [all] Error 2
-------------------------------------------------

It seems to result in an incomplete build, as the gnome-sharp-2.0 package 
is left uninstalled as a result. This is flagged as a problem if I then 
try and go ahead with the gtksourceview-sharp-2.0-0.10 configuration :

-------------------------------------------------
checking for gnome-sharp-2.0 >= 1.9.3... Package gnome-sharp-2.0 was not 
found in the pkg-config search path. Perhaps you should add the directory 
containing `gnome-sharp-2.0.pc' to the PKG_CONFIG_PATH environment 
variable No package 'gnome-sharp-2.0' found
configure: error: Library requirements (gnome-sharp-2.0 >= 1.9.3) not met; 
consider adjusting the PKG_CONFIG_PATH environment variable if your 
libraries are in a nonstandard prefix so pkg-config can find them.
-------------------------------------------------

>From what I can tell, this package ought to have been installed as part of 
the gtk-sharp installation :(

If anyone could lend any assistance I'd be very grateful.

Thanks.
