Dear Thiago,
I checked your command, and it works fine. As Steve said, your RCurl might be old. However, I changed that line based on Matteo's suggestion, to avoid the server connection error, and new version is uploaded on the website.
Best wishes,
Babak

Dear Barak,
If you are also accepting suggestions about errors, please let me share my experience with your script. I have received an error which appears to be related to a argument of package RCurl. Below, please take a look at my attempt to use your script:
> setwd("/Users/thiago/Downloads/MODIS/images/")
> source("/Users/thiago/Downloads/MODIS/ModisDownload.R")
> GPP <- "ftp://e4ftl01.cr.usgs.gov/MODIS_Composites/MOLT/MOD17A2.005/"
> MRT <- "/Applications/MRT/bin/"
> library(RCurl)
Loading required package: bitops
> library(raster)
Loading required package: sp
raster version 1.9-32 (24-October-2011)
> ModisDownload(FTP=GPP,h=c(10,14),v=c(7,14),dates=c("2010.01.01","2010.12.31"),mosaic=F,proj=F)
Error in download.file(url = paste(FTP, "/", dirs[i], "/", ModisName, :
cannot open URL 'ftp://e4ftl01.cr.usgs.gov/MODIS_Composites/MOLT/MOD17A2.005//2010.01.01/-rw-r--r-- 1 90 395831 Feb 4 2010 MOD17A2.A2010001.h10v07.005.2010035143552.hdf'
In addition: Warning message:
In mapCurlOptNames(names(.els), asNames = TRUE) :
Unrecognized CURL options: ftplistonly
Looking at the script, this line seems to be the source of the error:
getlist <- strsplit(getURL(paste(FTP,"/",dirs[i], "/", sep=""), .opts=curlOptions(ftplistonly=TRUE)), "\r*\n")[[1]]
And checking the arguments of curlOptions, "ftplistonly" doesn't appear to be available:

Any tips?
Thank you and best wishes,
