[Glass] Cannot load Metacello nor Glass in Glass itself (spot bug)

The github downloads aren't very good at providing good error messages ...
I have recently (in last month) improved some of the error handling for
github, but those improvements are only in the github repo and if you can't
download from github then you probably aren't using them...

But your use case of running multiple glass users (at the linux level) is
probably not accounted for  in the github implementation so additional work
needs to be done there to accomodate multiple users on the same machine
using Metacello ...

I've submitted a metacello bug[1] to track the issue ...

Until I can fix the bug, you the code  there are a number of methods that
make the assumption that /tmp can be used as a temporary dumping ground for

  MCGitHubRepository class>>projectDirectoryFrom:version:

Presumably these methods could be hacked to replace the use of '/tmp' with
a suitable image-specific replacement ... where you can set the root temp
directory to something that works for you ... this is probably the route I
will take for the final solution ...
