R help - Jun 2000 - postscript device on R-1.1.0

Am I the only one with this problem?  
> postscript()
Error in old$command == "default" : comparison (1) is possible only
for
vector types

The function postscript() is creates a list called "old".  the
function
wants to access old$command, but old does not have a component called
command.
> postscript
function (file = ifelse(onefile, "Rplots.ps",
"Rplot%03d.ps"),
    onefile = TRUE, ...) 
{
    new <- list(onefile = onefile, ...)
    old <- check.options(new = new, name.opt =
".PostScript.Options",
        reset = FALSE, assign.opt = FALSE)
    if (old$command == "default") 
        old$command <- if (!is.null(cmd <-
getOption("printcmd")))
            cmd
        else ""
    .Internal(PS(file, old$paper, old$family, old$bg, old$fg, 
        old$width, old$height, old$horizontal, old$pointsize, 
        old$onefile, old$pagecentre, old$print.it, old$command))
}
> temp_check.options(new=list(onefile=T), name.opt
".PostScript.Options", reset=F, assign.opt=F)
> names(temp)
 [1] "paper"      "horizontal" "width"     
"height"     "family"
 [6] "pointsize"  "bg"         "fg"        
"onefile"    "print.it"
[11] "append"     "pagecentre"

postscript works if I change 
  if (old$command == "default")
to
  if (is.null(old$command)) 


and another problem with R-1.1.0, 

if "./configure --gui=gnome" tells you it didn't configure gnome
support,
run "./configure" before doing "make" and "make
install".

./configure told me it wouldn't install gnome support, as I'm  
missing some libraries. After doing "make" and "make
install", R wouldn't
plot on an x11 window.  it works fine after re-running ./configure.

Yes, but that's not what is intended. You have a file .PostScript.Options
around somewhere in a saved workspace.  Just use

.PostScript.Option$command <- "default"

to update it, or delete it and use ps.options() to re-create it.
