All,
I have refresh the sources and binaries for the OpenGrADS Bundle on
sourceforge:
https://sourceforge.net/project/showfiles.php?group_id=161773&package_id=305032&release_id=662661
The main changes are:
1) A bug has been fixed in the UDX interface which was causing "exec
script" to fail. This is an important one, please update.
2) I have revised the internals of the Bundle implementation so that
it should work now with USB flash drives.
As of this writing, most binaries have been updated except for
FreeBSD 7 (FreeBSD 6.3 has been updated). Make sure the files you
download start with "grads-2.0.a5.oga.2" (notice the "2" at the end.)
Let me know of any problems.
Enjoy,
Arlindo
