The 'destdir' parameter defines where the packages get installed to.  The
default is '.libPaths()[1]' (which is generally going to be
'<path-to-R>/library').  

getBioC() checks to see if this directory exists using the call:
file.access(destdir,mode=0)

If that returns a negative value, it complains that the destdir directory
does not exist and halts.  So the first thing to check is if 'R:/libraries/gm'
actually does exist on your system ...
