What was the error and what did you change to fix it?

Probably you have installed PROJ.4 into a location that is not searched by
your system by default for the executable programs and shared libraries.
Especially if it is in /usr/local/lib make sure /usr/local/lib is in your
LD_LIBRARY_PATH environment variable, or on Linux you may also list it in
/etc/ld.so.conf and run ldconfig.

This would be a general Unix query, not GRASS specific. Maybe we should add a
note in the documentation on pre-requisites to make sure and install them
into a directory that your system searches for shared libraries.

It can't find libproj.so.0 in one of the locations it looks for shared
libraries (LD_LIBRARY_PATH or /etc/ld.so.conf; see above)
