It was looking for a file in a subdirectory that existed a level down so I made a symlink to try and work around that and the second attempt made it much further before bombing out.

Here is a solution in order to be able to use MrSid within FGS as long
as you are aware of the license terms.
I attached two object files and a shell script. Extract it under
$FGS_HOME/lib. Download Geo_DSDK-184.108.40.2067.linux.x86.gcc41.tar.gz at
your prefer location and run "sh mrsid_ld.sh" in $FGS_HOME/lib.
It should work without to download the FGS 9.5 VM.
