It will call the executable I want, but it finds OGR/GDAL library references that were not part of the current GDAL build. They appear to be the ones that come installed with IDL. An example:

Depending on the flavor of Linux, you may need to appending your shell's LD_LIBRARY_PATH onto the beginning of your SPAWN command, or spawn a script that's responsible for setting LD_LIBRARY_PATH first.

Compare and contrast :
$ echo $LD_LIBRARY_PATH

IDL> print, getenv('LD_LIBRARY_PATH')
