GEOGCS["unnamed",
    DATUM["unknown",
        SPHEROID["unnamed",6378137,298.2572235630001]],
    PRIMEM["Greenwich",0],
    UNIT["degree",0.0174532925199433]]

grass version :6.2.3
os: andLinux (ubuntu version)

I made Project Locatio by using EPSG code at start menu.
code no: 4030 <wgs84>

----
line and point data peojection as follows;

v.info shoreline
Projection: Lat/Lon (zone 0)
           N: 45.478 S: 41.462
           E: 145.778 W: 139.839

v.info investigation_points
Projection: Lat/Lon (zone 0)
           N: 45.526 S: 41.352

I *think* that you picked the wrong EPSG code. If you want
LatLong-WGS84, then use EPSG 4326.
