I had quite an adventure also. Here my findings:

* In addition to that (for me it worked only when) I moved the v0eur
(that is the whole folder) somewhere where all parent directories DO NOT
contain capital letters (!)


* Then query for example:
ogrinfo gltp:/vrf/home/nik/v0eur/vmaplv0/eurnasia 'polbnda at bnd(*)_area'
-al


* Extract with:
ogr2ogr polbnda.shp
gltp:/vrf/home/nik/v0eur/vmaplv0/eurnasia'polbnda at bnd(*)_area'

Hope this helps.
