genapts and libnurbsf.so.0

Gidday. I'm running into difficulties when following through your 
scenery tutorial on the terragear website. At the part where it says:
$ cd airports
$ genapts --input=default.apt.gz --work=../../work/ --min-lon=-80 
--max-lon=-70 --min-lat=40 --max-lat=50

I get this error:
glenn@upstairs airports $ genapts --input=default.apt.gz 
--work=../../work/ --min-lon=-80 --max-lon=-70 --min-lat=40 --max-lat=50
genapts: error while loading shared libraries: libnurbsf.so.0: cannot 
open shared object file: No such file or directory

libnurbsf.so.0 exists under /usr/local/lib as a symbolic link pointing 
to libnurbsf.so.0.1.0 in the dame directory. Moving libnurbs.so.0 
manually from it's source dir into /usr/local/lib doesn't do anything.

Another question. I don't have a Airports/default.apt.gz but I do have a 
runways.dat.gz. I'm assuming they are the same thing. Anyway, this isn't 
the source of the problem.

Any hints? I've installed the cvs version of Terragear with gpc and 
nurbs++ with it. Oh, and I originally sent this message to the wrong 
list, sorry.

Thanks,
Glenn
