Compiling elegant: nlpp not found

[JoelFrederico]

When trying to compile elegant (linux_x86-64) I get:

joelfrederico@ubuntu:~/oag/apps/src/elegant$ make
make -C O.linux-x86_64 -f ../Makefile TOP=../../.. T_A=linux-x86_64 install
make[1]: Entering directory `/home/joelfrederico/oag/apps/src/elegant/O.linux-x86_64'
nlpp ../save_lattice.nl save_lattice.h
make[1]: nlpp: Command not found
make[1]: *** [save_lattice.h] Error 127
make[1]: Leaving directory `/home/joelfrederico/oag/apps/src/elegant/O.linux-x86_64'
make: *** [install.linux-x86_64] Error 2

Where do I get nlpp? The closest I've found is the "native language programming project", which only seems to be a windows program, I'm not sure what I'm missing.

Simple mistake, I had environment variables only partially set to x86-64.
