Yes.  If you set an environment variable R_PDFVIEWER to the full name
of the kGhostView executable before configuring and building R.

Alternatively you could create a file Renviron.site in the R_HOME/etc
directory that defines R_PDFVIEWER to be the full name of the
kGhostView executable (usually something like /usr/bin/kghostview).
