Likely your PATH variable is set incorrectly. From within R you should
be able to do something like

 "c:\\Program Files\\Microsoft SQL Server\\100\\DTS\\Binn\\"
 "C:\\Program Files\\Graphviz2.20\\bin"
 "C:\\Program Files\\SAS\\SharedFiles\\Formats"

 "lefty.exe" "libcairo-2.dll"
 "libcdt-4.dll" "libcgraph-4.dll"
 "libexpat.dll" "libfontconfig-1.dll"
