Dear all,
I have installed R on Linux/Ubuntu 8.04. When I try to load the tcltk
package, I get the response:

> library(tcltk)
Error in firstlib(which.lib.loc, package) :
  Tcl/Tk support is not available on this system
Error in library(tcltk) : . First.lib failed for 'tcltk'

In order to solve this problem, I try to:
1. To download the tcl and the tk packages (version: 8.5) from
http://www.tcl.tk and to install them (the -dev packages also), but the
error hold over.
2. To install the previous releases (version: 8.4) for these packages. The
error hold over.
3. To set the environment variables 'TCL_LIBRARY' and 'TK_LIBRARY', in this
mode:
TCL_LIBRARY=/usr/local/lib/tcl8.5 *  (or 8.4)*
TK_LIBRARY=/usr/lib/tk8.5           *(or 8.4)*
but the error hold over.
4.Therefore, after this modifications, i uninstalled R and I installed again
it. I try to do this both without setting environment variables and setting
it. The error hold over.
I look for a solution.

Thank you

Davide Massidda
