[R] Problems to make work Tcl/Tk library (UNIX).

[Ortega, Carlos (Carlos)]

Dear R-Help,

I am starting to use R in a Unix machine:
++++++++++++++++++++++++++++++++
> R.Version()
$platform
[1] "sparc-sun-solaris2.6"

$arch
[1] "sparc"

$os
[1] "solaris2.6"

$system
[1] "sparc, solaris2.6"

$status
[1] ""

$major
[1] "1"

$minor
[1] "1.1"

$year
[1] "2000"

$month
[1] "August"

$day
[1] "15"

$language
[1] "R"
++++++++++++++++++++++++++++

and when I try to run the Tcl/Tk demo I get an error message:

++++++++++++++++++++++++++++
> require(tcltk) || stop("tcltk support is absent")
Loading required package: tcltk 
Error in dyn.load(x, as.logical(local), as.logical(now)) : 
        unable to load shared library
"/tools/GNU/R/1.1.1/lib/R/library/tcltk/libs/tcltk.so":
  ld.so.1: /tools/GNU/R/1.1.1/lib/R/bin/R.bin: fatal: libtcl8.3.so: open
failed: No such file or directory
Error in .C("delTcl", PACKAGE = "tcltk") : 
        C/Fortran function name not in load table
Error in eval.with.vis(expr, envir, enclos) : 
        tcltk support is absent
++++++++++++++++++++++++++++

Although I have Tcl/Tk (8.3) installed, I am not sure if this problem is due
to a improper compilation/configuration when R was installed or if the
problem is due to a missing environment variable.

Based on the error message, which are the alternatives we have ?
Re-compile and install with the adequate flags linking to the Tcl/Tk libs ?
or Is it possible to set environment variables to indicate where the Tcl/Tk
libs are available ?.

Hope that it is something very basic !

Thanks in advance.
Carlos.
