In this particular case, it appears that you have not set you GADDIR environment variable set correctly (assuming this is an installation based on COLA binaries). From COLA's download page:</div>

The font and map files are supplementary data sets that are required in order to run GrADS. Their default location is:<code><span class="code" style="font-family: 'Courier New', Courier, mono; font-size: 10pt; font-style: normal; font-weight: normal; ">/usr/local/lib/grads/. </span></code>If you do not have write permission for this directory you can place the files elsewhere, but you must also change the environment variable <code class="code" style="font-family: 'Courier New', Courier, mono; font-size: 10pt; font-style: normal; font-weight: normal; ">GADDIR</code> so the GrADS executables will know where to find these files. You can download the data files separately by clicking here: <a href="ftp://grads.iges.org/grads/data2.tar.gz"><code class="code" style="font-family: 'Courier New', Courier, mono; font-size: 10pt; font-style: normal; font-weight: normal; "><span class="plaintext" style="font-family: Arial, Helvetica, sans-serif; font-size: 10pt; font-style: normal; font-weight: normal; "><b>data2.tar.gz</b></span></code></a> <a href="ftp://grads.iges.org/grads/data.tar.Z"><code class="code" style="font-family: 'Courier New', Courier, mono; font-size: 10pt; font-style: normal; font-weight: normal; "><span class="plaintext" style="font-family: Arial, Helvetica, sans-serif; font-size: 10pt; font-style: normal; font-weight: normal; "><b></b></span></code></a>.</p>
