I recommend you do it the way wine does, putting the wrapper script  
into the files directory. It's easier to read the script that way,  
and easier to edit.

The script would then be "psppire.in" and would look like this:


#!/bin/bash

export OLDPWD=`pwd`
cd /tmp
LD_LIBRARY_PATH=@PREFIX@/lib/pspp ${prefix}/libexec/pspp/psppire
cd $OLDPWD


In the post-destroot you would use xinstall -m 755 to put it into $ 
{destroot}${prefix}/bin/psppire with the right permissions and then  
use reinplace to change @PREFIX@ to the real install prefix.


Do you ever need to pass command line arguments to the psppire  
program? If so, see how the wine port handles that.
