[Shotwell] Compile errors from master

[Jørn Villesen Christensen <shotwell mettle dk>]

Hi there,

I just tried to compile shotwell again from source. Grabbed master from 
git (clean checkout) and started compiling. After a few missing 
dependencies, I get this linker error:

  CCLD     src/shotwell-graphics-processor
src/.libs/libgraphics-processor.a(src_libgraphics_processor_la-_transformation.o): 
In function `pixel_transformer_apply_transformations':
/home/jvc/Dev/shotwell/src/_transformation.c:55: undefined reference to 
`_pixel_transformer_apply_transformations'
src/.libs/libgraphics-processor.a(src_libgraphics_processor_la-_transformation.o): 
In function `pixel_transformer_apply_transformation':
/home/jvc/Dev/shotwell/src/_transformation.c:74: undefined reference to 
`_pixel_transformer_apply_transformations'
collect2: error: ld returned 1 exit status
Makefile:2739: recipe for target 'src/shotwell-graphics-processor' failed
m

I don't quite know how to solve this... is there a kind soul that could 
point me in the right direction?
