[Twisted-Python] More trial problems with 8.0.1

[Brian Granger]

Hi,

Earlier today I posted about a problem with trial.  I reinstalled
8.0.1 and the origianl problem has gone away.  Now I get the following
error.  It appears that trial is trying to write something to the
plugins directory.  But that doesn't (and shouldn't) have the correct
write permissions.  I can run trial with as sudo, but not as a regular
user.  Isn't it bad practice to rely on being able to write to
site-packages at runtime.  Shouldn't such things do into a .twisted
directory or something like that?

Brian

Here is what I get
