Hi, Mark.
Thank you for repporting the bug.

I use gcc 4.1.1, under FedoraCore 5, to tell the truth I think I didn't 
compiled gdcm in static since ages ...
While linking Example/WriteDicomAsJPEG in static, I get the following error.
(You miss an external symbol, on your computer, I get it twice on mine:-( )

So, for a while, better you go on with shared libs ...
