wow -- What OS?  Are you sure on the absence of quoting around 
_BuySellArrows()_? -- Properly, it neds to be something like 
this on my test host:

#!/bin/sh
#
#
#
cd /home/herrold/build/gt
Scripts/graphic.pl                                      \
        --add="Curve(Indicators::EMA 5,[255,0,0])"      \
        --add="Curve(Indicators::EMA 20,[0,0,255])"     \
        --add="BuySellArrows(Systems::Generic           \
                {Signals::Generic::CrossOverUp          \
                {I:EMA 5} {I:SMA 20}}                   \
                {Signals::Generic::CrossOverUp          \
                {I:SMA 5} {I:SMA 20}} )"                \
