ITK/Release 4/DICOM/Tcon 2011 05 20

System gdcm

our fork of ITK is now stable, we keep the GDCM warnings ON in our copy time to address them. then we will switch main ITK back on.
building our branch of itk against linux, mac and windows:
- < drew put the name of the machines on the dashboard here >
- < each meeting should start or include browsing those machines and discuss remaining bugs/warnings >
- would anyone contribute buildhosts for that? We are missing windows buildhosts for ITK anyway.

fix library naming problem
fix library linking problem (modularization design shortcoming - thanks Brad K. for patch)
fix buildhosts
