The problem is that libgvc.so.3 is not in your dynamic library search path. That's true by default for FC5, it is in /usr/lib64/graphviz on a x86_64 FC5 box.
The proper solution is to fix the FC5 graphviz installation to tell ld.so about the location. A simpler way is to add /usr/lib64/graphviz to the LD_LIBRARY_PATH: on our servers we have edited R_HOME/etc/ldpaths to do so, so we have : ${R_LD_LIBRARY_PATH=${R_HOME}/lib:/usr/local/lib64:/opt/export/lib64:/usr/lib6 4/graphviz} If you don't have permissions to do this, set it in your personal LD_LIBRARY_PATH. BTW, asking questions about installing Bioconductor is best done on their mailing list, not R-help.
