I don't have too much of an idea about this, but perhaps the above
directory where your libproj.so is installed isn't in one of the
directories where your system looks for shared libraries?
Meaning you would have to add /usr/local/src/proj/src/.libs to your
LD_LIBRARY_PATH environment variable, or on Linux add it to
/etc/ld.so.conf and run ldconfig. Or else install PROJ properly so the
library libproj.so is in one of the standard system directories for shared
libraries.

Maybe the GRASS environment should set a special LD_LIBRARY_PATH to take
care of things like this? I know I needed to set it manually to be able to
use the GRASS 5.1 shared libraries on IRIX.

Somebody reported this before for d.where but said they had proj installed.

I can't think what else it would be other than the system not finding the
shared libraries.
