Problem: Bioconductor 2.6 version doesn't work with yeast. 
After upgrading R to 2.13 and GeneAnswers to bioconductor 2.8 Error message while loading library: libcdt-4.dll not found.
Solution: Install Graphviz, then add the location of the libcdt-4.dll to your windows path. For Windows XP, My Computer -> Properties -> Advanced -> Environmental Variables button -> Edit. Append a semicolon and the directory with the dll (on my system: C:\Program Files\Graphviz2.20\bin).
