A (potential) user is trying to help with testing a portfile
I've developed, mythtv-core.25, but we're having a problem.
Originally, I've emailed him the Portfile and related support
files. He is running Lion Server with the latest MacPorts
installed. He was able to install qt4-mac +mysql (a dependency).
When he attempts to install Myth, all of Myth's dependencies ARE
installed but then it aborts with the following error:

Earlier, he was connecting to this machine via Apple Remote
Desktop and I thought perhaps that was creating the permissions
problem. He is now working directly on the box so I think that
was a red herring.
Could someone help us figure out was is going wrong?
MacPorts was modified some time ago to drop privileges to an
unprivileged user (the "macports" user). While this change is nice
for ensuring that ports don't go modifying files on your system
that they're not authorized to modify, it throws a kind into our
instructions for how to install from random Portfiles located
anywhere on your disk, since the "macports" user probably won't
have permission to read files in your home directory.
OK, but:
1) MacPorts already read the Portfile to process the dependencies?!?
Since you're running MacPorts with "sudo", it starts off as root
with full access to all files. I'm not sure at what point it drops
down to the macports user.
2) I should have included that permissions seem to allow Everyone to read:
That file, yes, perhaps. But every directory leading up to that
file? I suspect not. In particular I suspect /Users/whatever is
readable by that user only.
Excellent point--I'll check about that.
Offline, it was suggested to modify macports.conf and change the
macportsuser to root. I'm having the user have a go at that.
