[OSRS-PROJ] nad27->nad83 conversion error in nad2nad.exe

[Boris Furman]

Hello,

I installed PROJ.4 package on my Windows 2000 box. I can ran proj.exe:

bash-2.02$ cd /work/geoconv/proj-4.4.2/src
bash-2.02$ ./proj.exe +init=nad27:2001 +units=us-ft
-70d36'30.872 41d38'54.192 A residence
843640.74       237542.45 A residence

But when I try to run nad2nad.exe I get the following error:

bash-2.02$ ./nad2nad.exe -i 27 -o 83 -r conus
Rel. 4.4.2, 15 July 2000
<nad2nad.exe>:
datum file: conus, failed: no system list, errno: 2

program abnormally terminated

Would you please point me to what I am doing wrong?

Thank you,

Boris Furman
