I'm testing on Leopard, PPC, for what that's worth.
Do you have a quick link for that NGA data?
You can get it from:
https://www1.nga.mil/ProductsServices/NauticalHydrographic/NauticalCharts/Pages/default.aspx
though the download site appears to be down at the moment.
Here is the one I'm trying:

Christopher,
There were 2 meaningful changes mades in the OGR OGDI driver during GDAL 1.7
development (http://trac.osgeo.org/gdal/changeset/18499 and
http://trac.osgeo.org/gdal/changeset/18502)
Could you try downloading and unzipping
http://freefr.dl.sourceforge.net/project/ogdi/OGDI_Test_Suite/3.1/ogdits-3.1.0.zip
then try :
ogrinfo -ro gltp:/vrf/path/to/ogdits-3.1/data/vpf/vm2alv2/texash
This is supposed to work (tested in GDAL autotest suite)
If it doesn't, then I'd suppose it is an issue with the OGDI library in the
framework.
It it works with that dataset, then perhaps this is due to one of the above
changes in the driver that wouldn't work with DNC datasets, but I'm very
skeptical as the changes only affect the layer object whereas your error
would tend to think that the driver doesn't even go to the point of creating
any layer.
Best regards,
Even

William,
I couldn't see a place to report this on your site, to I'm reporting it
here. The 1.7 GDAL build doesn't seem to support the OGDI drivers,
whereas the 1.6 build does.
I'm using ORG to read the VPF, as used by the NGA digital nautical
charts. Note:
$ /Library/Frameworks/GDAL.framework/Versions/1.6/Programs/ogrinfo
gltp:/vrf/Users/cbarker/Temp/DNC16/A1610880
yields:
ERROR 4: OGDI Driver doesn't support update.
Had to open data source read-only.
INFO: Open of `gltp:/vrf/Users/cbarker/Temp/DNC16/A1610880'
using driver `OGDI' successful.
1: build...@cul(*)_point (Point)
2: co...@cul(*)_point (Point)
....
Whereas:
$ /Library/Frameworks/GDAL.framework/Versions/1.7/Programs/ogrinfo
gltp:/vrf/Users/cbarker/Temp/DNC16/A1610880
yields:
FAILURE:
Unable to open datasource `gltp:/vrf/Users/cbarker/Temp/DNC16/A1610880'
with the following drivers.
-> ESRI Shapefile
...
-> OGDI
...
So OGDI is in the list, but it doesn't work.
Note that I'm having trouble getting this to work with my own build,
too, so it may be a GDAL/OGR/OGDI issue, rather than an issue with your
Framework builds.
