Thank you for that.
I need to get the people with the OS X problems to look at that. As I don't run
OS X myself (I prefere Solaris), it's hard to say.
I know Sage ships a Fortran compiler for OS X, but I'm not sure if there is more
than one of them.
On thing Sage tries to do is build binaries which will run on as wider range as
platforms as possible. It seems that getting a binary to run on PPC and well as
the latest OS X is just impossible.
What is odd, is that the code in Sage was working until we upgraded Numpy and
