Hey. i can't compile my gtk sourceview application

Heres the code:

I compile with these options

gcc -Wall -o srcview srcview.c \ > `pkg-config --cflags --libs gtk+-2.0 gtksourceview-1.0`

but get this output from GCC:

Package gtksourceview-2.0 was not found in the pkg-config search path.
Perhaps you should add the directory containing `gtksourceview-2.0.pc'
to the PKG_CONFIG_PATH environment variable
