[MonoDevelop] Error compiling gtksourceview

[Kevin Dietz]

Trying to get monodevelop compiled.  Been following all instructions 
carefully.  Haven't gotten very far.

For GtkSourceView, when I do the ./configure --prefix=/usr, I get ...

.
.
.
checking for gtk+-2.0 >= 2.3.0
         libxml-2.0 >= 2.5.0
         libgnomeprint-2.2 >= 2.2.0... Requested 'gtk+-2.0 >= 2.3.0' but 
version of GTK+ is 2.2.1

configure: error: Library requirements (gtk+-2.0 >= 2.3.0
         libxml-2.0 >= 2.5.0
         libgnomeprint-2.2 >= 2.2.0) not met; consider adjusting the 
PKG_CONFIG_PATH environment variable if your libraries are in a 
nonstandard prefix so pkg-config can find them.

I don't know what to do to get past this.  Suggestions?  I don't mean 
to complain, but is there a better set of installation notes somewhere?

Thanks.
