On an x86 machine operating under Gentoo Linux, I'm having trouble with tcltk in R-2.6.1 (the latest version available through Gentoo's emerge/portage system). The problem first came to my attention when "install.packages("Rmetrics")" produced the following error message: Loading required package: tcltk Error in firstlib(which.lib.loc, package) : Tcl/Tk support is not available on this system Error: package 'tcltk' could not be loaded Then I tried "library(tcltk)" and again got the last 3 lines shown above. Doing "emerge --search tcl" shows that dev-lang/tcl 8.4.18 and dev-tcltk/tcllib 1.6.1 are installed. I would be most grateful for suggestions for diagnosing and fixing this problem.
