Please check if you have by chance PROJ libraries twice on your system
(maybe a leftover from a local compilation vs distro packages.

sudo updatedb
locate libproj

may be of help here. Also check the output of

ldd $(which g.region)

for anything suspicious.

Please check (with locate, see above) if the library is on your system.

Mhh, weird. Maybe an error caused by another error?

I want that, too :-)
For the time being, here is a 3rd party search interface
