Hi William. So,
git clone --branch=2.5 https://github.com/dmtcp/dmtcp.git
will probably work for you. We'll set up a 2.5.0-rc2 for future users.
For the additional note, below, do you mind if I copy your report
from the latest e-mail into a github issue? By default, I'll give
credit to you as "William Fox" (no e-mail address). But I can do that part
however you wish.
We're between spring and summer semester here, but we hope to look
at this seriously in the summer.
Thanks,
- Gene

Mobile security can be enabling, not merely restricting. Employees who
bring their own devices (BYOD) to work are irked by the imposition of MDM
restrictions. Mobile Device Manager Plus allows you to control only the
apps on BYO-devices by containerizing them, leaving personal data untouched!
