[gentoo-science] can't emerge sage because a dependency is not in portage

[sitquietly]

For the past several weeks I've found it impossible to emerge sage from the 
sage-on-gentoo overlay because the ebuild for sage-5.2 (~amd64) and 
sage-5.3_beta2 (masked) requires ~dev-python/networkx-1.6.  However 
networkx-1.6 is not in portage any longer; networkx-1.2 is in the overlay and 
networkx-1.7 is in portage.

sage-5.1 had a networkx-1.6 specific patch but I don't see any patches in 
sage-5.2 that are networkx specific.

Should I copy the sage ebuild into my local overlay and change the dependency 
to networkx-1.7?  I'd be glad to be warned if any one knows of any problem I 
would encounter before I invest the time to try emerging sage to use the newer 
version of networkx.

I also was wondering why dev-python/networkx is required; I thought that 
networkx was integrated into sage?

Hi,

I don't really understand how it comes that you don't have network-1.6
in your tree. It's definitely still there:
http://sources.gentoo.org/cgi-bin/viewvc.cgi/gentoo-x86/dev-python/networkx/

The point of sage-on-gentoo is two fold:
1) system integration
2) complete unbundling
sage-5.1 in the overlay had a patch because upstream was still at
networkx-1.2 and I wanted to switch early since the patch was ready to
go for sage 5.2. sage 5.2 uses networkx-1.6 by default. I don't remember
testing if 1.7 was ok. But 1.6 is in the tree.

Thank you for your patient reply.  I'm using Funtoo and am surprised to find 
that networkx-1.6 is missing from the Funtoo portage tree.  I'll take that up 
on the Funtoo support forum.  I thought I had properly checked the Gentoo 
portage tree but apparently didn't know how to use the web interface properly.  
From now on I'll just keep a real Gentoo portage tree on my system alongside 
the Funtoo tree.

I look forward to enjoying the sage overlay now.

Ah! We certainly don't mind funtoo users but the fact should be
disclosed early on. That would have avoided me some head-scratching.

Funtoo seem to be very keen on keeping to the latest "and greatest"
so it is unsurprising to me. Please keep us informed on the difficulties
and success you have with s-o-g on Funtoo. We don't mind the extended
audience at all.
