[Rd] Rexcelpoi

I was experimenting with Rexcelpoi from Armstrong Whit.  I was able to 
compile the package in my Redhat linux machine with a few warnings but 
no errors.  I was not able to get the package built on my windows xp 
computer, but that is for another post.

I load R on the linux computer and type in the library call to Rexcelpoi 
the receive the following error.


  *** caught segfault ***
address (nil), cause 'memory not mapped'

  1: dyn.load(file, ...)
  2: library.dynam(lib, package, package.lib)
  3: loadNamespace(package, c(which.lib.loc, lib.loc), keep.source = 
  4: doTryCatch(return(expr), name, parentenv, handler)
  5: tryCatchOne(expr, names, parentenv, handlers[[1]])
  6: tryCatchList(expr, classes, parentenv, handlers)
  7: tryCatch(expr, error = function(e) {    call <- conditionCall(e) 
  if (!is.null(call)) {        if (identical(ca       ll[[1]], 
quote(doTryCatch)))             call <- sys.call(-4)        dcall <- 
deparse(call)[1]        prefix <- paste       ("Error in", dcall, ": ") 
        LONGCALL <- 30        if (nchar(dcall) > LONGCALL) 
prefix <- paste(prefi       x, "\n\t", sep = "")    }    else prefix <- 
"Error : "    msg <- paste(prefix, conditionMessage(e), "\n", sep = "") 
           .Internal(seterrmessage(msg[1]))    if (!silent && 
identical(getOption("show.error.messages"),         TRUE)) { 
    cat(msg, file = stderr())        .Internal(printDeferredWarnings()) 
    }    invisible(structure(msg, class = "try       -error"))})
  8: try({    ns <- loadNamespace(package, c(which.lib.loc, lib.loc), 
keep.source = keep.source)    dataPath <- file.p 
ath(which.lib.loc, package, "data")    env <- attachNamespace(ns, pos = 
pos, dataPath = dataPath)})
  9: library(Rexcelpoi)

Possible actions:
1: abort (with core dump, if enabled)
2: normal R exit
3: exit R without saving workspace
4: exit R saving workspace

Some things I can figure out, but this one is beyond my capabilities. 
Any thoughts or suggestions are greatly appreciated.  If you think the 
build warnings are important, I can rebuild the package and post those.

Everyone have a wonderful day.

Thank you
