In addtion to working with v.in.e00, I have also tried Shaun's  
suggestion of using avcimport manually (creates 6 .adf files), then  
using v.in.ogr to import. I'm getting the same error "Cannot open  
data source".

GRASS 6.1.cvs (arrowhead_utm):~ > v.in.ogr dsn=~/Desktop/tmp/ 
glo10ktest/  out=glo10ktest
ERROR: Cannot open data source:
        /Network/Servers/truffula.fr.umn.edu/Volumes/disk1/home1/ 
kwythers/Desktop/tmp/glo10ktest/

This is probably caused by the same issue that was giving the  
v.in.e00 script fits. Any other thoughts?
