Hi John,
Replying to [comment:14 jhpalmieri]:
> A few installation issues: it requires database_gap, but if I download
that spkg and install it from the downloaded version (that is, using "sage
-i path_to/database_gap-4.4.10.spkg" rather than "sage -i
database_gap-4.4.10", which downloads the file), then its installation is
recorded in SAGE_ROOT/spkg/installed, but not in SAGE_ROOT/spkg/optional,
which is where your spkg-install looks.
I didn't know that. IIRC, the part of spkg-install that checks for the
presence of the database is more or less copied from the Developer's
Guide. So, do you think I should look in both locations?

This is bad. I have never seen this error message. In particular, I don't
know what is meant by "Resource temporarily unavailable": Is there a race
condition?
If I am not mistaken, Intel Mac running 10.5 was one of the platforms
where installation of the previous version worked. However, David Joyner
said that in one case (I think on a MacBook) things only worked when
trying to install for the second time, see
[http://trac.sagemath.org/sage_trac/ticket/6491#comment:41] and the
preceding comments. Of course, it would be good to understand why that
happens sometimes.
How could one try to sort out these problems? Unfortunately, I have no
access to an Intel Mac.
Best regards,
Simon
