Why should you convert the script to tcsh? IMHO the best way is to
convert it to sh.

recursive declaration?

Yep, it's not defined at the time [1] occures. Actually, defining
LD_LIBRARY_PATH almost always is a Bad Thing.

1. Create a port (local?) for the software. Don't forget to brand
   executables (only!).

2. Install it to PREFIX=/usr/local (i.e. libraries to /usr/local/lib
   etc), linuxulator will make the right thing to find needed
   libraries.

3. Delete the definition of LD_LIBRARY_PATH.

4. Enjoy you work. ;-)
