The trick from the "svn timeout on qnx pkgsrc checkout" thread didn't
work for me, so I set up a read-only mirror (svnsync from SourceForge
works consistently).

It also has a seed file, which should speed initial local repo
creation a lot, especially if you want the whole tree.

I have a cron job set up to update it nightly. There is a mailing list
you can go on to get email when there is an update. Or you can do the
usual built-in SourceForge notifications by using the RSS icon and/or
"Update Notifications" button.

Main site:
https://sourceforge.net/projects/qnxpkgsrcmirror/

Mailing list:
https://lists.sourceforge.net/lists/listinfo/qnxpkgsrcmirror-notifications

Let me know if there are any problems.
