[R] ffnet problem

[v.demartino2@virgilio.it]

Context:Linux debian testing, compiled R 1.9.0 from source.

I've just installed the contributed ffnet package wit no problem at all.
But when loading the library the following error message is popping up and
no ffnet command seems to work:

>library("ffnet")
Error in dyn.load(x, as.logical(local), as.logical(now)) : 
	unable to load shared library "/usr/local/lib/R/library/ffnet/libs/ffnet.so":
  libstdc++.so.2.8: cannot open shared object file: No such file or directory
Error in library("ffnet") : .First.lib failed
......................
What should I do?
Ciao
