Some more info: According to /usr/share/doc/proj/README.Debian, "The Debian proj package includes built-in datum conversion. (It was compiled with proj-datumgrid-1.3.zip unpacked in the nad source directory.)"
According to the proj.4 FAQ (http://trac.osgeo.org/proj/wiki/FAQ): "Verify that you have the binary files (eg. /usr/local/share/proj/conus) installed on your system." It seems that the package does not include /usr/local/share/proj/conus, according to "dpkg -L proj", though it does have some other files there. Also from the FAQ, there's a PROJ_DEBUG environment variable. Setting this I get: $ cs2cs +proj=latlong +datum=NAD27 +to +proj=latlong +datum=NAD83 pj_open_lib(proj_def.dat): call fopen(/usr/share/proj/proj_def.dat) - succeeded pj_open_lib(proj_def.dat): call fopen(/usr/share/proj/proj_def.dat) - succeeded -117 30 pj_open_lib(conus): call fopen(/usr/share/proj/conus) - failed pj_open_lib(alaska): call fopen(/usr/share/proj/alaska) - failed pj_open_lib(ntv2_0.gsb): call fopen(/usr/share/proj/ntv2_0.gsb) - failed pj_open_lib(ntv1_can.dat): call fopen(/usr/share/proj/ntv1_can.dat) - failed 117dW 30dN 0.000 So it does seem that it's the absence of this /usr/share/proj/conus file that's the problem. Has it been accidentally omitted from the build, perhaps? I also consider the fact that the program silently continues and prints a wrong answer when it has detected that the file is missing to be a bug.
