[GRASS-user] importing bil file errors

[Tyler Smith]

Following-up on my own question, I *can* view the raster in Grass 6.4, so it did get imported. So I guess the problem is with the display in grass 7. 

I tried to update to the latest version of 7 from svn, but it failed to build with a pile of errors, so I can't check that.
