[gentoo-science] running sage 4.4 the first time

Hi,

got everything installed now, but when sage first runs (e.g. during
post-install of the ebuild) it tries to perform inits and spawns a lot
of gap processes. their all look like this:

root     25781 25769  0 15:29 pts/5    00:00:00 /bin/sh
/usr/local/bin/gap -r -b -p -T -o 3900m /opt/sage/data//extcode/gap/sage.g

root     25782 25781  0 15:29 pts/5    00:00:00 bash /opt/sage/sage -gap
-r -b -p -T -o 3900m /opt/sage/data//extcode/gap/sage.g

root     25785 25782  0 15:29 pts/5    00:00:00 bash
/opt/sage/local/bin/sage-sage -gap -r -b -p -T -o 3900m
/opt/sage/data//extcode/gap/sage.g

As you can see here there are a lot of these...

denkmatte archtest # ps -ef | grep sage | wc -l
1780

Naturally load goes up a lot and this does not seem to finish.
Any ideas?

Regards,
Thomas

That looks like the problem Marek and others already had - this happens only 
on amd64. What is interesting: "/usr/local/bin/gap" shouldnt this be 
"/usr/bin/gap" - without local ?

Hmm, interesting. I have an old version of sage in /usr/local/sage ...
and this installed /usr/local/bin/gap. Tricky.

By the way, I am on x86, but I think the above explains the issues... I
will see if it works after cleanup.

Thanks
Thomas
