Hi Felipe,

Thanks for your response.
Just to report my experience :

I downloaded the package via svn.
First I modified the fcl-version needed. Then I had to remove a unit 
(rawvectorialreadwrite.pas) from the package before I could compile it. 
I don't remember the error but it was on the line containing
lRawImage.Description.Init_BPP24_R8G8B8_BIO_TTB(RAW_IMAGE_WIDTH, 
RAW_IMAGE_HEIGHT);

Then, unfortunately, none of the examples seem to work. Only two I could 
compile : fpcorelexplorer, but when I run it, it gives a "list index out 
of bounds" error after selecting a coreldraw 9 file. Then it gives 
correctly the version of the coreldraw used, but no size. I don't know 
what it's supposed to do more.
fpvectorialconverter gives an "unsupported vector graphics format" error 
when I select a pdf and click to visualise it.

fpv3dviewer gives "identifier not found" on RequireDerivedFromResource.
fpvmodifytest and fpvwritetest give errors on a bunch of "WSRegister..." 
statements.

That's all with the latest release version of lazarus/fpc, on Windows 7. 
I'll have to see if I can get a working lazarus from svn.
