Hello,
I just installed R-2.15.0 on windows XP and cannot load package tcltk2
(which I just downloaded from CRAN as tcltk2_1.2-1.zip; package install
reported no problems):

> library(tcltk2)
Carico il pacchetto richiesto: tcltk
Loading Tcl/Tk interface ... done
Error : .onLoad failed in loadNamespace() for 'tcltk2', details:
  call: system("cat /etc/issue", intern = TRUE, ignore.stderr = TRUE)
  error: 'cat' not found
Errore: package/namespace load failed for ‘tcltk2’
It seems .onLoad is trying to run a unix command 'cat' but i'm on a windows
platform:
> str(.Platform)

attached base packages:

I looked for an R file in the tcltk2 installed package tree containing the
above system() call but could not find it.
This looks like a bug to me but I'd like to ask for further advice before
reporting it as such, I might have overlooked something. Thanks for any
help.
