You should put the path to where your "epsg" file resides into the
"Path to the EPSG codes file" dialog. The file comes with PROJ.4.

Your gdalinfo output seems corrupted. Compare with the output of
"epsg_tr.py 4326" to see the difference. It is missing EPSG codes for
prime meridian and unit. That's propably why GRASS fails to creata a
location using it.

Also please note that only the last EPSG code designates the coordinate
system. Those coming before it are for the CS components, like
spheroid, datum etc.

That's because you are passing wrong EPSG coordinate system code, which
GRASS 6.2 can't handle and creates a corrupted location. As expected,
only "4326" works OK. In GRASS 6.3, using an invalid coordinate system
EPSG code yields an error message like on the attached screendump.
Please fill in a wish in the tracker for backporting this usefull
feature to GRASS 6.2. Maybe it will get included in 6.2.2 release.
