It seems that there is no mechanism to install a library as addon. It is
also possible that something is missing in the Makefile for r.pi.library
because that library is unknown to the GRASS make system.

the addons directory is supposed to hold executables and scripts, not
libraries. At least I could not find a mechanism in the grass startup
script where LD_LIBRARY_PATH is adjusted to also include some directory
within the addons directory. I am not sure if it is worth the trouble to
modify the addons mechanism to support addon libraries, particularly if
only the r.pi suite is affected.
