Hi Andrew,

welcome to scipy-dev :)  You may want to subscribe to continue this discussion 
on-list.

Scipy-dev: I'm forwarding here info from a colleague, regarding build 
information on Itanium machines.  A bit of info about the hardware:

~>uname -a

[repeated 4 times, it's a 4-cpu box]

Travis et al: I have access to these boxes and I'm upstairs from Andrew, so 
I'll be happy to help with further testing of this.  Along with Arnd's work on 
the opterons, it would be great if we could confirm that upon release, 
scipycore/new both build and pass all tests both on Opteron and on Itanium.

Andrew's original message follows unmodified.

Cheers,
