I am trying to install GrADS 2.2 on a new Ubuntu (64-bit) system. I have followed all steps from the INSTALL file and when I try to run the executable, I get the following error:</div>
<div style="font-family: Calibri, Helvetica, sans-serif; font-size: 16px; margin-top: 0px; margin-bottom: 0px;">
</div>
<div style="font-family: Calibri, Helvetica, sans-serif; font-size: 16px;"><i>/home/weather/grads/bin/grads: error while loading shared libraries: libpng15.so.15: cannot open shared object file: No such file or directory</i></div>

</div>
<div style="font-family: Calibri, Helvetica, sans-serif; font-size: 16px; margin-top: 0px; margin-bottom: 0px;">
What might I be doing wrong?</div>
