R help - May 2011 - Installation of rattle complains about missing packages

Hi,

if I try to install rattle, R fails to install:

rpvm, rsprng, RBGL, pcalg, arulesViz, pkgDepTools, Rgraphviz .

rpvm depends on pvm,  rsprng on sprng which is not installed and which
seems not so easy to install on my gentoo systems.  ArulesViz depends on
Rgraphviz, RBGL and pcalg depends on graph, which is like Rgraphviz and
pkgDepTools not available.


Is there any hint how to proceed?

Regards
Juergen
