Podofocolor (latest library compiled with no errors on Mac) gives me
this error when opening CMYK colorspaced PDF:

> podofocolor lua ../podofo-0.9.5/tools/podofocolor/example.lua 
> ff_ff-gs-cmyk-icc.pdf ff_dummy.pdf 
>

(it doesn't matter what parameters I call podofocolor with, e.g.
grayscale etc) 

  and gives me this error when opening RGB colorspaced PDF: 

> podofocolor lua ../podofo-0.9.5/tools/podofocolor/example.lua ff_ff.pdf 
> ff_dummy.pdf
> <</Info 198 0 R/Root 199 0 R/Size 200>>

  Any help would be really appreciated. I doubt a C(++) program will
rescue me e.g. open a PDF, change colors in it and save it.
