I actually was successful (see the following code, but with the \array environment code commented out).  This code produced what I was looking for.  Unfortunately, when I then put the simple code into a larger document that contained several  equation and array environments I get an error.  If I set through the error, the arrays that are printed are pretty mangled.  I have searched the web (mostly ctan and pstricks) but cannot find anything useful.  If I was to guess, I would have to say that there is an incompatibility between the arrayjob pack and the basic array environment, but I really don't know.

use a simple macro instead.

\def\xlabel#1{\ifcase#1 Jan\or Feb\or Mar\or Apr\or May\or Jun%
	\or Jul\or Aug\or Sep\or Oct\or Nov\or Dec\or Jan\fi}

%\begin{postscript}%
   \psset{yAxisLabel=Beta Angle (degrees),xAxisLabel={Time (months)},%
     xAxisLabelPos={5cm,5.5cm},yAxisLabelPos={-1.cm,9cm},
	llx=-2cm,lly=-2cm,urx=0.5cm,ury=0.5cm}%
   \begin{psgraph}[axesstyle=frame,xticksize=0 30,yticksize=0 366,
	Dx=30,Dy=10,Oy=40,xAxis=false](0,40)(366,70){10cm}{5cm}%
     \readdata{\datafile}{./datafile1.dat}%
     \listplot[linecolor=red]{\datafile}%
     \multido{\nt=0+30,\i=0+1}{13}{\rput{90}(\nt,37){\xlabel{\i}}}%
   \end{psgraph}%
