GDAL not available in MODIS R package?

I am trying to analyze the MODIS EVI 250m, 16day dataset. I found the R MODIS package and am following the instructions here: https://conservationecology.wordpress.com/2014/08/11/bulk-downloading-and-analysing-modis-data-in-r/

But when I try to run the runGDAL function it tells me that:

library(MODIS)
dates1 <- as.POSIXct( as.Date(c("01/01/2015","31/12/2015"),format = "%d/%m/%Y") )
dates2 <- transDate(dates1[1],dates1[2])
product <- "MOD13Q1"

h = "25"
v = "07"
runGdal(product=product,begin=dates2$beginDOY,end = dates2$endDOY,tileH = h,tileV = v,SDSstring = "111", outProj="4326")

However I get the error:

Error in runGdal(product = product, begin = dates2$beginDOY, end = dates2$endDOY, : GDAL not installed or configured, read in '?MODISoptions' for help

I tried using the checkTools() command to set GDAL:

MODIS:::checkTools("GDAL")

Checking availabillity of GDAL: OK, GDAL 1.11.3, released 2015/09/16 found!

Does anybody have any ideas on how to fix this issue?

I'm using MODIS version 0.10.33. Output of MODISoptions():
