A minor configuration issue in the 3.3.26 and 3.4.1 worker-node tarballs
prevented the GFAL tools from functioning. We have created updated
tarballs with the correct configuration.
If you installed OSG worker-node tarballs directly, between July 12th and
18th, you should consider reinstalling them using the latest builds
(labeled as version 3.3.26-2 or 3.4.1-2). The tarball installations
on OASIS have been updated.
