Jan,
Is EPSG location creation the only thing that fails? Can you create
locations from georeferenced files and by specifying projection
parameters?
I just tried creating a location from EPSG code 4326 and it worked
fine in GRASS 6.3 compiled a few days ago. I don't know if this is a
problem related to 6.2 or not
Glynn Clements discussed a problem with shared libraries in Linux
that might or might not be a help. I am copying it below.
Michael

Most systems won't load shared libraries from /usr/local/lib without
some additional configuration.
For Linux, you need to either set the LD_LIBRARY_PATH environment
variable to a path which includes /usr/local/lib, or add
/usr/local/lib to /etc/ld.so.conf then run ldconfig (as root).
