[GRASSLIST:4555] existing libgdal.so.1 library not found by startup script ps.map

Even after installing the libgdal.so.1 library in the folder usr/bin/ I receive the following message after starting grass57:

Error in startingup script: ps.map: error while loading share libraries: libgdal.so.1: cannot open shared object file: No such file or directory while executing...

Also the Display manager does not start from the GRASS menue. As I understood right from my investigations on the web these seem to be related problems.

But what do I have to do to solve them?

A LINUX and GRASS Newbie

Even after installing the libgdal.so.1 library in the folder usr/bin/

usually libs are kept in /lib, /urs/lib and /usr/local/lib

if you install your libs into /usr/local/lib then add this path to the
/etc/ld.so.conf and run 'ldconfig' as root
