Even though everything seems to install alright, I get an error message:

g.extension r.pi
Fetching <r.pi> from GRASS GIS Addons repository (be patient)...
Compiling...
Installing...
make[1]: *** No rule to make target 'install'.  Stop.
Updating addons metadata file...
Installation of <r.pi> successfully finished

I imagine this due to the fact that I run GRASS directly from the source 
directory and not from ?

But when I try to install it using the system-wide installation (Debian 
package, grass-dev is installed), I get:

g.extension r.pi
Fetching <r.pi> from GRASS GIS Addons repository (be patient)...
Compiling...
/usr/bin/ld: cannot open output file 
/usr/lib/grass74/lib/libgrass_rpi.7.4.0.so: Permission denied
collect2: error: ld returned 1 exit status
make[1]: *** [/usr/lib/grass74/lib/libgrass_rpi.7.4.0.so] Error 1
/bin/sh: 1: cannot create /usr/lib/grass74/error.log: Permission denied
make: *** [r.pi.library] Error 2
ERROR: Compilation failed, sorry. Please check above error messages.

i.e. it tries to install the lib into the system-wide installation 
directory, not the user .grass7/addons directory.

Removing also doesn't seem to work:

g.extension r.pi op=remove -f
ERROR: Unable to remove file
        '/home/mlennert/.grass7/addons/docs/man/man1/man1/r.pi.corr.mw.1'

but

I guess we need some more work on how to handle these suites...
